Pane Nero di Castelvetrano (Castelvetrano Black Bread)

Pane nero di Castelvetrano is the dark, sesame crusted loaf of the Belice valley in western Sicily. Its colour comes from nothing but the grain: stone milled tumminia, an ancient durum wheat, raised with a natural leaven until the crumb turns the shade of wet earth.

The crust is thick and crackling, the crumb moist and lightly sour. This is a bread of patience, not difficulty.

Yield: 1 loaf, about 16 slices. Total: about 26 hours with leaven and cold proof. Difficulty: intermediate. Region: Sicily.

The Story

Castelvetrano sits in the Belice valley, in the province of Trapani, a plain of wheat, olive groves and vineyards that runs from the hills down to the Greek temples of Selinunte and the sea. The valley is best known abroad for its bright green Nocellara olives, but for the people who live there the defining product is bread. Pane nero, black bread, is the loaf of the farm kitchen and the village oven, and its dark crumb has been the local signature for as long as anyone can trace.

The grain behind it is tumminia, also called timilia, one of the oldest durum wheats in Sicily. The name is usually traced to trimenia, three months, for the short cycle of a crop sown in early spring and cut in June. It grows tall, yields little and suits neither the combine harvester nor the fast roller mill, which is exactly why it nearly vanished. Its flour is not white but a warm tawny brown, and it smells of hazelnut and dried grass. Through the twentieth century farmers replaced it with higher yielding varieties, and only a handful of families kept sowing it, milling it on stone and baking it in wood fired ovens.

The revival came from those families and from the bakers who refused to sift the bran out of their flour. A Slow Food presidium now protects the bread and the growers who supply it, and tumminia has become a small emblem of Sicilian food memory. The loaf itself was always practical. Baked in large rounds, it stayed good for a week or more in a farmhouse without refrigeration, and the sourdough leaven that raised it kept the crumb moist far longer than a white loaf raised with yeast could manage. Today small bakeries across the valley still sell it by weight, often still warm in the morning, and locals buy a whole loaf without a second thought.

It was eaten in the fields with olive oil, salt and oregano, torn over ripe tomatoes, wrapped around a slice of fresh tuma cheese, or dipped into the broth of a bean soup. The sesame crust, common across Sicilian bread, is often credited to the Arab centuries, when sesame arrived on the island with almonds, citrus and sugar cane. Together the seed and the earthy grain make a loaf that tastes of Sicilian history and of one plain valley in particular. A slice with nothing but oil and salt remains the honest way to taste it.

Ingredients

Weigh everything on a digital scale. Whole grain flours vary widely by volume, and the cup measures below are only a guide. Tumminia flour is sold as semola integrale di tumminia or farina integrale di tumminia by Sicilian mills and specialty shops. Semola rimacinata is durum semolina milled twice to a fine flour, not the coarse pasta semolina. If you cannot find it, use good bread flour, but expect a paler, milder loaf. Use a starter that is fed regularly and active, not one forgotten in the refrigerator.

For the leaven

Ripe sourdough starter, lievito madre, 2 tbsp (30 g)
Semola rimacinata di grano duro, 1/3 cup (60 g)
Water, 1/4 cup (60 ml)

For the soaker

Whole grain tumminia flour, semola integrale di tumminia, 3 3/4 cups (450 g)
Water, 1 3/4 cups (420 ml)

For the dough

Ripe leaven from above, all of it
Semola rimacinata di grano duro, 1 3/4 cups (300 g)
Water, 1/2 cup (120 ml)
Fine sea salt, 1 tbsp (18 g)

For the crust

Sesame seeds, natural, 1 cup (140 g)
Semola rimacinata for the banneton, 2 tbsp (20 g)
Water for misting, in a spray bottle

For serving

Extra virgin olive oil, Sicilian, 1/4 cup (60 ml)
Flaky sea salt, 1 tsp (3 g)
Dried Sicilian oregano, 1 tsp (1 g)
Ripe tomatoes, 2 medium (300 g)
Fresh tuma or ricotta salata, 6 oz (170 g)

Preparation

Build the leaven

Ripe semolina sourdough leaven with a domed bubbly surface.

Mix the starter, the 1/3 cup (60 g) of semola and the 1/4 cup (60 ml) of water in a clean jar until smooth. Cover loosely and keep it at 78°F (26°C) for 8 to 10 hours, until it has doubled, domed and smells pleasantly sour rather than sharp. Use it at the peak, before it collapses. A spoonful dropped into water should float.

Soak the tumminia

Hydrating whole-grain tumminia flour for the soaker.

Stir the whole grain tumminia flour and 1 3/4 cups (420 ml) of water together until no dry flour remains. Cover and leave it at room temperature for at least 2 hours, or overnight in the refrigerator. It thickens into something like wet clay. Add no salt and no leaven yet.

Mix the dough briefly

Briefly mixing the tumminia dough by hand.

Scrape the soaker into a large bowl, add the ripe leaven, the 1 3/4 cups (300 g) of semola and the remaining 1/2 cup (120 ml) of water. Work it by hand for about 3 minutes, only until no dry pockets remain. Rest 30 minutes, then sprinkle over the salt and fold it in with a wet hand for 1 minute. The dough will be dark, sticky and slightly shaggy. That is correct.

Fold and ferment

Gently stretching and folding the fermenting whole-grain dough.

Keep the dough at 78°F (26°C) for 4 to 5 hours. During the first 2 hours give it four sets of stretch and folds, 30 minutes apart: with a wet hand lift one edge, stretch it up and fold it over the centre, turn the bowl a quarter and repeat four times. Then leave it alone until it has grown by about half and shows a few bubbles. It will not double. The folds should feel like lifting a soft elastic sheet, so stop each set when you meet resistance.

Shape the loaf

Shaping the dough into a taut round loaf.

Turn the dough onto a bench dusted with semola. Fold the edges to the middle to make a loose round, cover and rest 20 minutes. Then drag the round toward you against the bench, turning it, until the surface is taut and the loaf holds its dome. Work firmly but quickly and do not press out all the gas.

Coat with sesame and proof cold

Coating the damp loaf in sesame seeds before cold proofing.

Spread the sesame on a tray. Mist the loaf lightly, or wipe it with a damp towel, and roll it in the seeds until fully coated. Lower it seam side up into a banneton dusted with semola. Cover and refrigerate for 10 to 12 hours. The cold slows fermentation, deepens the flavour and firms the loaf, which makes it far easier to score.

Bake with steam

Baking the scored sesame loaf in a Dutch oven.

Heat a covered Dutch oven at 475°F (245°C) for 45 minutes. Tip the cold loaf onto parchment, score one deep slash 1/2 inch (12 mm) deep, lower it into the pot and cover. Bake 25 minutes, uncover, lower the oven to 425°F (220°C) and bake 25 to 30 minutes more, until the crust is nearly black at the ridges, the loaf sounds hollow and the centre reads 208°F (98°C). Use oven gloves, since the pot and the lid are dangerously hot.

Cool completely

Cooling the whole Castelvetrano loaf completely on a wire rack.

Move the loaf to a wire rack and leave it for at least 3 hours before cutting. The crumb is still setting inside, and a warm loaf slices gummy and smears against the knife.

Plating

Cut the loaf into slices 1/2 inch (12 mm) thick with a serrated knife and serve at room temperature on a wooden board, with the crust side facing out so the sesame shows. Place a small bowl of good Sicilian extra virgin olive oil beside it, a dish of flaky sea salt and a pinch of dried oregano.

For a more composed plate, top the slices with sliced ripe tomato and fresh tuma or ricotta salata, or serve a wedge next to a bowl of bean soup. Warm the plates only slightly. A hot plate softens the crust. Cut thick slices for the tomato and thinner ones for cheese and oil, so each topping meets the right amount of bread. Sprinkle the flaky salt over the tomato, not the bread, to keep the crust crisp.

Professional Technique

Everything about this dough follows from one fact: tumminia is an ancient grain, and its bran cuts the gluten. Whole grain tumminia flour has a weak gluten network to begin with, and the flakes of bran in it are sharp and abrasive. Prolonged kneading drags those flakes through the network and physically severs the gluten strands as they form. So the dough is mixed for only 3 minutes, never in a machine, its strength comes from four gentle sets of folds, and the tumminia is soaked in advance.

The soak is the essential step. Bran is thirsty, and bran that meets water only after it touches gluten steals that water from the network and cuts it at the same time. Given 2 hours or a whole night alone in its own water, the bran drinks its fill and softens, and by the time the flour meets the leaven its edges no longer cut.

There is also a ceiling. In this formula tumminia is a little over half of the total flour, with fine semola rimacinata supplying the remainder. Past about 70 percent of the flour the network is too thin and shredded to hold gas, and the loaf bakes into a dense, flat disc however long it ferments.

This is also why the bread needs lievito madre and not brewer's yeast. Commercial yeast makes gas within hours, before the bran has softened and before folds have built any structure, so the gas escapes through a torn network. The natural leaven works slowly and makes lactic and acetic acids, which firm the gluten that is there and slow the enzymes in the germ that would otherwise dissolve it. Time and acidity do the work that kneading cannot.

Texture and Moisture Control

Steam decides the crust. In the sealed Dutch oven the surface of the loaf stays wet for the first 25 minutes, so the dough keeps stretching and the loaf springs to its full height before a shell can form. Once the lid comes off and the temperature drops, dry heat sets the crust, browns the sesame and drives the crust toward the deep colour of the ridges. A pale crust means it came out too soon.

The crumb is kept moist by hydration. At roughly 75 percent water, the dough is wetter than it feels, and the whole grain flour holds that water through the bake. The result is a tight, custardy crumb with small irregular holes, not an open one. Do not chase big bubbles with more water or longer fermentation.

Cooling is part of the bake. Inside the loaf the starch is still gelatinized and loose while it is hot, and it firms as it cools. Cutting early releases steam and leaves the crumb wet and sticky. After cutting, keep the loaf cut side down on the board so the crumb stays soft while the crust stays crisp for a day.

Professional Mise en Place

This bread is a two day project, but almost all of it is waiting. Organise it so the only work on baking day is the oven and the board.

Equipment and tools

Digital scale, since whole grain flours vary by volume
Large mixing bowl and a jar for the leaven
Banneton, 9 inch (23 cm), and a linen cloth
Covered cast iron Dutch oven, 5 quart (4.7 L)
Razor blade or lame, instant read thermometer, wire rack, spray bottle

Prepared ahead

Leaven built the morning before
Tumminia soaked overnight in the refrigerator
Loaf shaped, coated and proofing cold for up to 14 hours
Sesame measured into its tray
Semola for the banneton and the bench portioned

Service setup

Loaf baked at least 4 hours before service
Board, serrated knife and linen ready
Olive oil, salt and oregano in small bowls
Tomatoes and tuma sliced only at the last moment, with a clean dry knife
Oil poured into its bowl 10 minutes ahead so it reaches room temperature

Chef Tips

Buy tumminia from a mill that stone grinds it and check the date. The germ oils in whole grain flour turn stale within a few weeks, and an old flour gives a bitter, cardboard note that no leaven can hide.

Judge the dough by feel and by volume, not by the clock. Cool kitchens can need 6 hours of bulk fermentation and warm ones only 4. Look for growth of about half and a slightly domed, glossy surface.

Toast a little of the sesame first in a dry pan for 2 minutes if you want a stronger nutty flavour. Raw seeds bake to a light gold. Toasted ones go deeper.

Score decisively and only once. A single deep, confident cut directs the oven spring, while several timid cuts tear the dark crust and leave ragged edges. Hold the razor at a low angle, about 30 degrees, and cut in one motion.

Common Mistakes

Kneading it like ordinary bread. A long knead or a stand mixer tears the weak network apart and leaves a dense, gummy loaf. Mix briefly, fold gently and let time do the rest.

Skipping the soak. Dry bran goes straight into the dough and takes water it should not, so the crumb bakes hard and crumbly. Give it at least 2 hours.

Using more tumminia to get a darker loaf. Past about 70 percent of the flour, the bread stops rising. The colour comes from the grain and the long bake, not from adding more of it.

Using an underripe or overripe leaven. One that has not doubled is too weak to lift this dough, and one that has collapsed is too acidic and turns the crumb sticky. Use it at its peak.

Scoring too shallow. A cut under 1/4 inch (6 mm) seals over in the oven and the loaf bursts at the side instead. Cut 1/2 inch (12 mm) deep.

Cutting the loaf while warm. The steam inside has not settled, so the crumb comes out gummy and wet. Wait 3 hours.

Wine Pairing

The bread is earthy, faintly sour and rich in olive oil and salt, so choose dry Sicilian wines with acidity and sapidity.

Etna Bianco DOC: Made mostly from Carricante grown on volcanic soil, it has brisk citrus acidity and a distinct mineral, saline finish. That freshness cuts through olive oil and lifts the nutty sesame without covering the taste of the grain. Serve it cold with tomatoes and tuma, at around 46°F (8°C).

Grillo Sicilia DOC: A western Sicilian white from the country around Trapani, with lemon, herbs and a saline edge. It matches the oregano and oil on the bread, and its medium body stands up to the dense, moist crumb without being heavy. Pour it just before the bread comes out of its cloth.

Cerasuolo di Vittoria DOCG: A blend of Nero d'Avola and Frappato that is a lighter, brighter red than most. Red cherry fruit, fresh acidity and supple tannin work with ripe tomato, cured meats and aged cheese laid on a thick slice, without overpowering the loaf. Serve it lightly chilled, around 57°F (14°C).

Etna Rosso DOC: Nerello Mascalese gives high acidity, fine grained tannin and a smoky, ashy note. It echoes the toasted crust, and its structure suits a slice topped with sausage or aged pecorino. Serve it slightly cool, around 60°F (16°C).

Avoid sweet wines and heavily oaked reds, which flatten the salt and oil that make the bread taste of Sicily. For a nonalcoholic option, sparkling water with lemon suits the loaf well.

Storage & Reheating

Keep the loaf cut side down on a board, or wrapped in a linen bag, at room temperature for up to 5 days. Do not refrigerate it, as the cold accelerates staling. Skip plastic, which softens the crust.

For the freezer, slice the loaf, wrap the slices in parchment and freeze in a sealed bag for up to 3 months. Toast slices straight from frozen. To revive a whole loaf that has gone firm, mist it lightly with water and heat it at 350°F (175°C) for 10 minutes. Stale bread is excellent in panzanella, ribollita and breadcrumbs.

If the crust softens after a day, put the whole loaf uncovered in a 400°F (200°C) oven for 6 to 8 minutes. The dry heat drives out surface moisture and the crackle returns. Never microwave it, which turns the crumb rubbery.
