Torcolo di San Costanzo is Perugia's yeast-raised bread-like ring, prepared here from the formula deposited in 2025 at the Chamber of Commerce of Umbria. Olive oil, sugar, citron, raisins, pine nuts, and anise define it; the yolk-brushed top has exactly five cuts. Shape it free-hand on a buttered and floured flat baking pan or sheet, never in a ring or tube pan. Makes one ring; serves 12. Active time: 45 minutes. Rise time: about 3 1/2 to 5 hours, with the second rise at least 2 to 3 hours and until well risen. Bake time: 40 to 45 minutes, plus more as needed. Total time: about 5 to 7 hours before cooling.
The baked ring has a burnished, lightly firm crust and a structured bread crumb with a tender chew. It should be moist without seeming greasy, with citron, raisins, and pine nuts distributed through every slice. This is not a soft sponge, frosted dessert, or buttery cake.
Perugia prepares and shares this Umbrian specialty on January 29, the feast of San Costanzo. Its ring shape, anise fragrance, fruit, nuts, and five surface cuts express the city's tradition. The 2025 deposited formula records the classic proportions and method used in Perugian homes, bakeries, and celebrations.
A proper torcolo keeps a clear ring, golden surface, and five shallow cuts. Its supple bread crumb holds evenly distributed inclusions without oily pockets or a compressed base. Anise and olive oil balance citron, raisins, and pine nuts; sweetness remains measured.
This professional version uses U.S. customary measurements first, followed by metric equivalents. Weigh the principal ingredients whenever possible, read the complete method before beginning and finish every element of mise en place before heat is applied. Regional Italian cooking depends on proportion: the named ingredient must remain recognizable, supporting aromatics must never dominate and finishing fat, cheese or sugar should carry flavor without forming a heavy layer.
Use sensory cues alongside time. Color shows whether browning is complete, aroma reveals whether wine, flour or garlic remains raw, and resistance reveals hydration or tenderness. Keep reserve liquid and clean tasting spoons available, choose a vessel large enough for unrestricted movement and taste a complete bite rather than an isolated sauce. Correct concentration before adding salt, then correct richness with measured acidity only when the traditional formula permits it.
For organized service, complete resting, cooling, long simmering and shaping stages first. Leave texture-sensitive finishing for the final minutes. Warm plates for savory food, use a cool board or plate for bread and pastry, and never hold a finished crisp surface longer than necessary. The result should appear effortless because temperature, moisture, sanitation and sequence were controlled in advance.
Ingredients
• 5 cups flour (600 g)
• 1 cup granulated sugar (200 g)
• 3 1/2 ounces candied citron, cut into small pieces (100 g)
• 4 1/4 ounces raisins (120 g)
• 3 1/2 ounces pine nuts (100 g)
• 1/3 ounce anise seeds (10 g)
• 7 tablespoons plus 1 teaspoon extra-virgin olive oil (100 g)
• 1 1/4 ounces fresh baker's yeast (35 g)
• About 1 1/4 cups warm water (approximately 300 g)
• 1 teaspoon fine sea salt (6 g)
• 1 large egg, separated, with the yolk reserved for the surface
• Butter and flour, as needed, for preparing a flat baking pan or sheet only
Preparation
1. Moisten the raisins separately, then drain and squeeze well; their water is not part of the dough water. Cut the citron small. Butter and flour a flat baking pan or heavy sheet. Do not use a ring or tube pan. Separate the egg; cover the reserved yolk. The white is unused.
2. Combine the 5 cups (600 g) flour and 1 teaspoon (6 g) salt. Soften fresh yeast in some measured warm water, then add it. Gradually incorporate remaining water to bread-dough consistency; the stated 1 1/4 cups (approximately 300 g) is intentionally approximate.
3. Knead this plain first dough for several minutes, until uniform and cohesive. Cover the bowl with a cloth or food-safe wrap. Leave it in a warm place protected from drafts until the dough has doubled in volume. Use the visible doubling, not a guessed clock time, as the requirement for proceeding.
4. Turn the doubled dough out. Add olive oil, sugar, citron, squeezed raisins, pine nuts, and anise. Fold and press repeatedly until the oil and sugar enter the dough and the inclusions begin dispersing.
5. Knead the enriched dough for at least 10 full minutes. It may feel slippery initially; do not change the formula. Finish when cohesive, with citron, raisins, pine nuts, and anise distributed evenly.
6. Form the dough free-hand into a ring and join the ends securely. Transfer it directly to the buttered and floured flat baking pan or sheet, preserving the open center without any mold. Keep it in a warm, dry, draft-free place for the second rise for at least 2 to 3 hours. Continue the rise beyond that span whenever needed: proceed only when the ring is visibly well risen while still holding a defined shape.
7. Near the end of the second rise, preheat the oven to 356°F (180°C). Brush the risen surface evenly with the reserved egg yolk. With a sharp knife, make exactly five small, shallow cuts in the top. Do not make extra decorative slashes or cut deeply enough to deflate the ring.
8. Bake at 356°F (180°C) for 40 to 45 minutes, keeping the specified temperature rather than treating this like a conventional butter cake. At 40 minutes, begin checking for a richly golden, fully set surface and a baked center. If it is not done at 45 minutes, continue baking at 356°F (180°C), checking every 5 minutes rather than treating 45 minutes as a hard maximum. Slide the free-form ring from the baking pan or sheet to a rack and cool completely before slicing.
Professional Technique
Staged enrichment defines the method. Flour, salt, yeast, and water first become lean dough and double; only then are oil, sugar, fruit, nuts, and anise incorporated with at least 10 minutes' kneading. Shape a secure free-form ring on a flat pan or sheet. Rise it at least 2 to 3 hours and until well risen, brush lightly with yolk, and make exactly five shallow cuts.
For repeatable results, record ingredient temperatures, vessel size, final yield and the decisive doneness cue during the first preparation. These variables explain differences more accurately than the clock alone. Keep tasting utensils separate from raw-food tools, sanitize every surface after handling meat or eggs and use a calibrated instant-read thermometer whenever the method specifies a safety temperature.
Chef Tips
• Treat metric weights as the precision standard; weighing every principal ingredient protects the deposited proportions.
• Use water that feels warm but not hot. Fresh yeast must soften and disperse without heat that could weaken fermentation.
• Squeeze raisins thoroughly; surface water loosens the dough and tempts unnecessary flour.
• Keep both rises away from drafts. The first ends only at a true doubling; the shaped ring then rises for at least 2 to 3 hours and longer when necessary, because visible fullness—not the clock alone—determines readiness.
• Brush yolk thinly and count exactly five small, shallow cuts before baking.
• Use the pine nuts as supplied rather than dark-toasting them first; extended browning can make their exposed surfaces bitter during the 40-to-45-minute bake.
Common Mistakes
• Butter in the dough, glaze, or powdered sugar changes the preparation. Butter and flour belong only on the flat pan or sheet.
• Adding enrichments before the first dough doubles defeats the required sequence and weakens initial bread structure.
• Stopping the enriched knead early leaves oily streaks and clusters. Knead at least 10 minutes.
• Replacing 1 1/4 ounces (35 g) fresh yeast with dry yeast changes the stated formula; do not substitute uncalculated amounts.
• Shortening the second rise, stopping before the ring is well risen, making more or fewer than five cuts, or cutting deeply moves the result away from the deposited method. Bake at 356°F (180°C) for 40 to 45 minutes first, then continue as needed until fully baked.
• Holding the completed dish too long. Carryover heat, trapped steam and continued absorption can undo correct cooking after the pan leaves the stove.
Wine Pairing
Floral perfume, gentle sweetness and light effervescence echo anise and candied citron while keeping the olive-oil-enriched crumb buoyant. Serve well chilled at 43–46°F (6–8°C). Keep the pour measured so Torcolo di San Costanzo (Italian Umbrian Ring Cake) remains the focus.
Honeyed fruit, citrus-peel nuance and balancing acidity connect naturally with raisins, citron and pine nuts. Keep the wine sweeter than the torcolo and serve at 50–54°F (10–12°C). Keep the pour measured so Torcolo di San Costanzo (Italian Umbrian Ring Cake) remains the focus.
Dried-fruit, toasted-nut and oxidative notes mirror the torcolo's raisins and pine nuts, while measured acidity prevents a heavy finish. Serve in a small pour at 54–57°F (12–14°C). Keep the pour measured so Torcolo di San Costanzo (Italian Umbrian Ring Cake) remains the focus.
Storage & Reheating
Cool the torcolo completely before wrapping it, or trapped steam will soften the crust and make the crumb tacky. Keep it tightly wrapped at room temperature for up to 3 days. For longer storage, wrap slices securely and freeze for up to 1 month; thaw while wrapped at room temperature. Refresh a slice briefly in a low oven, without glaze, butter, or powdered sugar.
Discard perishable food left at room temperature for more than 2 hours, or 1 hour above 90°F (32°C). Reheat only the portion needed, avoid repeated cooling cycles and keep crisp, creamy and sauced components separate whenever possible. Stored texture will not equal fresh service, so use controlled gentle heat rather than accelerating the process.
