Italian Tuscan Kale and Borlotti Bean Soup | Farinata di Cavolo Nero e Borlotti
Updated: Oct 24
Farinata is what happens when a Tuscan bean and cavolo nero soup has cornmeal rained into it and stirred until it thickens. It sits between a soup and a polenta, thick enough to hold the mark of a spoon but still loose enough to pour, and it is eaten with nothing on it but raw olive oil and black pepper.
Do not confuse it with the Ligurian farinata, the chickpea flour pancake baked in a copper pan in Genoa. They share a name and nothing else. This one belongs to the Tuscan interior, to the Valdarno, the Casentino and the Mugello, and in the Garfagnana the same dish is called infarinata. Every version rests on three things: borlotti cooked from dry, cavolo nero picked after the first frost, and stone ground yellow corn flour.
The technique that decides whether it works is the minute when the flour goes in. Rained slowly through the fingers into moving liquid it disperses and swells into a smooth body; dumped in, it seizes into lumps no stirring will break. Everything else is patience: beans properly cooked, kale stewed rather than blanched, and forty minutes of low heat so the corn loses its raw taste.
Yield: 6 servings. Prep: 25 minutes. Soak: 12 hours. Cook: 2 hours 30 minutes. Total: about 3 hours plus soaking. Difficulty: easy. Course: primo piatto. Region: Tuscany, the Valdarno, the Casentino and the Garfagnana.
The Story
Farinata comes out of the mezzadria, the sharecropping system that organised Tuscan country life from the Middle Ages until it was dismantled in the 1960s. A sharecropping family handed half of everything it produced to the landowner, and what stayed in the house was what the landowner did not want: dry beans, winter greens, and corn flour once maize spread through central Italy in the seventeenth century.
Cavolo nero is the ingredient that pins it to Tuscany. The tall dark leaf grows through the coldest months and is the same cabbage that goes into ribollita and into zuppa di pane, and Tuscan cooks insist it is not worth picking before the first frost. They are right, and there is a reason: cold weather makes the plant convert stored starch into sugars as an antifreeze, so a frosted leaf is measurably sweeter and less bitter than the same leaf picked in October.
The dish is built to be eaten twice. On the first day it is served hot and loose from the pot. What is left is poured into a shallow dish and refrigerated, where the gelatinised corn starch sets it firm enough to cut. Those slabs are fried in olive oil the next day until crisp outside and soft within, a second meal many Tuscans prefer to the first. The recipe was designed around that fact, not adapted to it.

Preparation
Step 1
Soak and cook the beans. Cover the borlotti with cold water by three fingers and leave them 12 hours, or overnight. Drain, put them in a pot with fresh unsalted water, the garlic, sage, bay and olive oil, and bring them to a bare simmer. Cook 60 to 90 minutes until fully tender, adding hot water if they surface. Salt only in the last 10 minutes, because salt added early toughens the skins. Cool them in their liquid and keep every drop: that cloudy broth is half the flavour of the dish.
Step 2
Pass part of the beans. Lift out about a third of the beans and pass them through a food mill with a ladle of their liquid until smooth. Leave the rest whole. This is what gives farinata its body before any flour is added, and why it is creamy without cream. Discard the garlic, sage and bay.
Step 3
Prepare the cavolo nero. Strip the leaves off the tough central ribs by hand and discard the ribs, which never soften. Wash the leaves in plenty of cold water, since grit lodges in their blistered surface, and shred them across into ribbons about 1/2 inch (1 cm) wide. A pound of untrimmed kale yields roughly 11 oz (320 g) of leaf.
Step 4
Build the soffritto. Warm the olive oil in a heavy pot over medium low heat and cook the onion, carrot and celery gently for 12 to 15 minutes until soft, sweet and barely coloured. Add the sliced garlic, rosemary and chilli for a minute, then the tomato paste, and cook it out until it darkens. Do not rush this: it is the only concentrated flavour in a dish with no meat in it.
Step 5
Stew the kale. Add the shredded cavolo nero to the pot in handfuls, turning each one in the oil until it collapses before adding the next. Once it is all in, cover and let it stew in its own moisture for 10 minutes. The leaves should go dark, glossy and soft. Never blanch the kale separately and add it later, which washes the flavour into water you then pour away.
Step 6
Combine and simmer. Pour in the bean puree, the whole beans, all the bean cooking liquid and enough water or stock to reach a loose soup consistency, about 6 cups (1.4 l) in total. Add the salt and plenty of black pepper, bring it to a gentle simmer and cook uncovered for 20 minutes so the flavours settle. Taste and correct the salt now, before the flour goes in, because seasoning a thickened farinata is much harder.
Step 7
Rain in the corn flour. Bring the soup to a lively simmer and stir it into a slow whirlpool with a wooden spoon. With the other hand let the corn flour fall through your fingers in a thin steady stream, never a scoop, keeping the spoon moving the whole time. Take a full 3 or 4 minutes to add it. If you see a lump form, break it against the side of the pot immediately, while it is still soft.
Step 8
Cook out the flour. Lower the heat to the barest simmer and cook 40 to 45 minutes, stirring every few minutes and scraping the bottom, because corn flour catches and burns without warning. Add hot water whenever it tightens past a thick pourable consistency. It is ready when it coats the spoon, pulls slightly from the side of the pot and tastes of sweet corn rather than raw flour. Rest it off the heat 5 minutes before serving.
Plating
Serve it in warm shallow bowls, not deep ones. Farinata is dense and cools from the surface down, so a wide bowl eats better than a narrow one of the same volume, and it lets the guest see the whole beans and the dark ribbons of kale.
Ladle it in and let it find its own level rather than smoothing it. Make a shallow dip in the centre with the back of the ladle and pour a teaspoon of robust green olive oil into it, then grind black pepper over the top. The oil is not a garnish here: it is added raw, off the heat, and its peppery bitterness is the one sharp note in a dish that is otherwise entirely soft and sweet. Put the bottle on the table so people can add more, and serve toasted country bread alongside.
Professional Technique
The core technique is hydrating corn flour without letting it clump, and the physics are simple. A granule that meets hot water gelatinises on the outside first, forming a skin that keeps water out of the dry core, so a spoonful tipped in seals itself shut. Rained in slowly over moving liquid, every granule hydrates on its own. This is why the stream must be thin, why the liquid must move, and why three minutes of patience saves twenty of futile whisking.
The second technique is splitting the beans into two textures. Passing a third through a food mill releases their starch into the broth and thickens it before any flour is involved, while the whole beans keep their skins and give the spoon something to find. Blend the whole batch and the corn flour turns the puree into paste; blend none and you get a thin broth with beans at the bottom, thickened by flour alone, which tastes flat.
Texture and Moisture Control
Farinata thickens three times and you must plan for all of them: as the flour gelatinises in the first ten minutes, again across the remaining half hour, and a third time between the pot and the table. Take it off the heat looser than you want to serve it, at roughly the consistency of a thick pouring batter. Keep a kettle of hot water beside the pot; cold water dropped into gelatinised starch chills it into a seam that never fully recombines.
The finished texture should hold a furrow drawn by the spoon for about two seconds before it closes. Faster than that and it is soup; if the furrow stays open it has gone too far and will set into a solid block on the plate. Corn flour that has not cooked long enough feels chalky on the palate no matter how thick it looks, and this is the most common fault in home versions, so judge it by taste rather than by appearance.
The cavolo nero needs its own control. Stewed in oil under a lid it releases moisture slowly and stays dark and silky; boiled hard in the finished soup it turns grey and loses its structure. Add it before the flour, never after, and keep the pot below a rolling boil once the corn goes in, to protect the kale and to stop the base catching.
Professional Mise en Place
Almost everything here can be done in advance. The only stage that demands undivided attention is the flour, and it lasts about four minutes.
Equipment and tools
Heavy bottomed pot, 6 quart (6 l), thick base to prevent scorching
Food mill with the medium disc, or a blender
Long wooden spoon and a flat edged wooden spatula for the bottom of the pot
Kettle of hot water kept beside the stove throughout
Shallow dish for setting the leftovers, for the fried version
Prepared ahead
Beans soaked overnight and cooked up to 2 days ahead, stored in their liquid
Soffritto vegetables diced fine the day before, covered and refrigerated
Cavolo nero stripped, washed and shredded up to a day ahead, kept dry and cold
Corn flour weighed into a jug with a pouring lip, ready for the rain in
Service setup
Bowls warmed, never cold, because farinata stiffens on contact
Good finishing olive oil decanted and on the table
Hot water at hand for loosening between the first and second helpings
Bread sliced and toasted at the last moment
Chef Tips
Buy stone ground corn flour rather than instant polenta. Instant grades are precooked and dried, and they hydrate in two minutes into something that tastes of nothing; stone ground flour carries the germ, needs the full 40 minutes, and is the reason this dish tastes of corn at all.
Never salt the beans at the start. Salt in the soaking or early cooking water firms the skins and they stay tough however long you boil them. Add it in the final 10 minutes and they will be creamy inside with skins that hold.
Keep every drop of bean liquid and use it as the base. Pouring it away and replacing it with stock is the difference between a farinata that tastes of the Valdarno and one that tastes of a cube. If you cook the beans a day ahead, refrigerate them in that liquid.
If you can only find young cavolo nero with no frost behind it, balance the extra bitterness with a pinch more salt and two more minutes of stewing in oil. Curly kale works at a push. Savoy cabbage does not: too sweet, too watery, and the dish loses its backbone.
Common Mistakes
Adding the corn flour too fast. This is the fault that ruins most attempts. A scoop tipped into hot liquid seals into lumps within seconds and they never break down. Rain it through your fingers in a thin stream over a moving whirlpool and give it three full minutes.
Undercooking the flour. Corn flour that has thickened is not corn flour that is cooked. Forty minutes at a bare simmer is the minimum, and anything less leaves a chalky raw taste that no seasoning hides. Judge it by tasting, not by how thick the pot looks.
Discarding the bean cooking water. That cloudy liquid holds the starch and most of the flavour the beans gave up. Throwing it out and using plain water or stock produces a thin, dull farinata that no amount of olive oil at the table can repair.
Blanching the cavolo nero separately. Boiling the leaves and draining them sends their flavour down the sink and turns them grey. Stew them directly in the soffritto oil under a lid so everything they release stays in the pot.
Leaving the central ribs in the leaves. The thick stems stay fibrous through two hours of cooking and are unpleasant in a dish that is otherwise smooth. Strip them out by hand before shredding.
Walking away from the pot. Thickened corn flour catches on the base without any smell of warning and a scorched bottom flavours the entire batch. Stir and scrape the bottom every few minutes throughout the final stage.
Wine Pairing
Chianti Rufina DOCG: The most convincing red for this bowl. Grown in the cooler hills northeast of Florence, Rufina keeps a higher natural acidity and a leaner frame than Sangiovese from warmer zones, and that acidity lifts a dish that is soft, starchy and low in fat. Its dried herb and sour cherry notes meet the rosemary in the soffritto, and the tannin is light enough not to clash with the faint bitterness of the kale.
Vernaccia di San Gimignano DOCG: The Tuscan white with enough structure to sit beside a thick soup instead of vanishing under it. It finishes on a distinctly bitter almond note that runs alongside the cavolo nero rather than fighting it, and its saline minerality picks up the raw olive oil poured on at the table. Serve it at around 50°F (10°C), not colder, or that texture closes up.
Romagna Sangiovese DOC: The everyday bottle for a peasant dish, and honestly proportioned to it. Lighter and more forward than its Tuscan cousins, with soft red fruit and gentle tannin, it refreshes between spoonfuls without asking for attention. Pour it cool, around 57°F (14°C), which sharpens its acidity and makes it read as a foil to the warm corn rather than another heavy element.
Orvieto Classico DOC: A neighbouring Umbrian white that works through restraint. Its blend of Grechetto and Trebbiano gives white peach fruit, modest alcohol and a clean bitter finish, and that restraint is the point: the farinata carries almost no acid of its own, so the wine supplies it without competing with corn and beans.
Storage & Reheating
Farinata keeps in an airtight container in the refrigerator for 4 days and improves overnight, as the corn and the beans finish settling into each other. It freezes for up to 3 months in portions; thaw it overnight in the refrigerator, never at room temperature. To reheat, put it in a saucepan over low heat with a few tablespoons of hot water and stir until it loosens and steams through, because the starch sets hard when cold and needs both liquid and movement to come back.
The second day version is the reason to make extra. Pour the hot leftovers into a shallow oiled dish about 1 inch (2.5 cm) deep and refrigerate overnight until firm enough to cut. Slice into slabs and fry them in a generous film of olive oil over medium high heat, 3 or 4 minutes a side, until crisp and browned outside and soft within. Salt them as they come out and eat them at once. Farinata left too loose will not hold its shape in the pan.
