Chestnut, Doce de Leite, and Roasted Brazil Nut Strudels

What Makes This Special

This strudel uses a true stretched dough for crisp, flaky layers, a filling with roasted chestnuts and Brazil nuts for autumn, and a coppery apricot glaze for visual impact and gift appeal. Doce de leite provides identifiable Brazilian character and moisture balance.

Ingredients

This recipe uses strong flour for extensibility, chestnuts for autumnal richness, Brazil nuts for regional specificity, and a sticky-sweet Brazilian filling held in check by roasted and ground nuts. The copper-toned glaze is for presentation. The dough needs to be stretched until nearly transparent for authentic texture.

For the Strudel Dough

• Bread flour: High protein for gluten development and stretch.
• Lukewarm water: Hydration for gluten.
• Neutral oil: Tenderizes the dough and helps stretching.
• Egg: Structure and elasticity.
• Salt: Strengthens gluten and balances flavor.

For the Filling

• Chestnuts: Roasted for a warm, starchy texture.
• Brazil nuts: Roasted for crunch, aroma, and structure.
• Doce de leite: Sweetness and moisture.
• Sugar, cinnamon, orange zest: Fragrance and flavor depth.

For Assembly and Glaze

• Butter: For laminating layers.
• Egg yolk + milk: For sheen and browning.
• Apricot jam, water, copper powder: Visual finish.

Instructions

Step 1: Make and Rest the Dough

Combine bread flour and salt in the bowl of a stand mixer. Whisk egg, water, and oil together. Pour wet into dry. Mix with dough hook on low until a rough dough forms (2 minutes). Increase speed to medium and knead 8–10 minutes, until very smooth and elastic. The dough must pass the windowpane test (stretch a piece to see if it becomes nearly transparent without tearing). Shape into a ball, lightly oil, cover, and rest at room temperature for 1 hour, then refrigerate overnight. This rest lets gluten relax and hydration equalize, making it extensible for stretching.

Step 2: Prepare the Filling

Preheat oven to 180°C. Spread chestnuts and Brazil nuts on a tray. Roast 10 minutes until fragrant. Cool, then pulse together in a food processor to a coarse meal (no larger than 3 mm pieces for Brazil nuts). Mix in cinnamon, sugar, and orange zest. Fold in the doce de leite to combine evenly. The mixture should be thick, slightly sticky, but spreadable. Set aside.

Step 3: Laminate the Butter Block

Cut cold butter into 5 mm slices. Arrange between two sheets of parchment and beat gently with a rolling pin to a 15 x 20 cm rectangle, 6 mm thick. Chill until firm but pliable.

Step 4: Stretch the Dough

Remove dough from fridge and allow to come to cool room temperature (20–22°C). On a floured cloth, roll the dough out as thinly as possible (approx. 60 x 80 cm), then gently stretch by hand from the center outward—supporting with the back of your hands—to transparency. You should be able to read print through the dough. Trim thick edges with a sharp knife.

Step 5: Assemble the Strudel

Lay the stretched dough on a floured cloth. Brush exposed surface with melted butter. Spread the nut-chestnut-doce de leite filling in a 10 cm wide strip 5 cm from the short edge nearest you, leaving 3 cm clear on the sides. Fold in the sides of the dough (to seal in the filling during rolling). Using the cloth, lift and roll the dough over the filling tightly, continuing to roll until fully enclosed. Transfer to parchment-lined baking sheet, seam-side down. Shape gently into a log.

Step 6: Chill and Slash

Refrigerate the shaped strudel for 20 minutes to firm up the dough and filling. Preheat oven to 200°C (convection). Whisk egg yolk and milk, brush the surface. Slash the top 4–5 times at a shallow angle to allow steam to escape. This prevents splitting during baking.

Step 7: Bake

Bake for 20 minutes at 200°C. Reduce oven to 170°C, rotate pan, and bake 20–25 minutes more or until deep golden and crisp (internal filling temp ≥90°C). The pastry should shatter when tapped. Cool on a rack for 30 minutes before glazing.

Step 8: Glaze and Finish

Heat apricot jam and water in a small saucepan until liquid. Strain, then brush over warm strudel. Dust with edible copper powder while still tacky for a metallic autumn sheen. Allow to set before slicing and packaging.

Pro Tips

• Stretch dough slowly and evenly; if it resists, rest 5–10 minutes covered, then continue. Over-stretching tears gluten, under-stretching ruins texture.
• Keep all layers dry and separated during assembly. Too much filling or wetness causes sogginess.
• Chill assembled strudel before baking so butter remains layered, producing maximum flake.

Troubleshooting

Strudel leaks filling or bursts: The dough was too thin or not sealed at the edges. Next time, reinforce seam and folds.

Pastry is chewy, not crisp: This means under-baking or under-laminating. Bake to full golden and confirm shattering crust.

Filling runs out: Too much doce de leite or insufficient nut mass. Use exact ratios and bind well.

Variations

• Replace chestnuts with roasted pumpkin or sweet potato for a different autumn filling.
• Add chopped candied ginger or dried fruits to filling for more texture.
• Glaze with maple syrup and sprinkle with toasted coconut for a different finish.

Storage

Store cooled, uncut strudel wrapped tightly in parchment and foil at room temperature for up to 2 days. For gifting, package whole and slice immediately before serving. Freeze slices individually for up to 2 months. Re-crisp in a 180°C oven for 10 minutes before serving.
