Dough (détrempe):
Bread flour (Weizenmehl Type 550) – 250 g
Sugar – 30 g (2 tbsp)
Salt – 5 g (1 tsp)
Fresh yeast (Bio Frischhefe) – 15 g (or 5 g instant yeast)
Buttermilk (your homemade) – 120 ml, cold
Water – 20–30 ml, cold (adjust as needed)
Butter – 15 g, softened
Butter block (lamination):
Homemade butter – 125 g, cold and pliable
Egg wash:
1 egg + 1 tbsp milk or buttermilk + pinch of salt
1. Dough prep (Evening – Day 1)
Dissolve fresh yeast in the buttermilk + water.
Mix flour, sugar, and salt in a bowl. Add yeast mixture + 15 g softened butter.
Knead 5–7 min until smooth. Dough should be firm, not sticky.
Wrap and chill in fridge for 30–45 min.
2. Butter block
Place 125 g butter between parchment.
Pound/roll into a 10×10 cm square.
Chill until firm but pliable.
3. Lamination (Folds)
Roll dough into a 20×20 cm square. Place butter block diagonally in the center. Fold dough corners over butter like an envelope. Seal edges. (This is the lock-in, not counted as a fold.)
Roll to a rectangle 20×60 cm. Fold in thirds (letter fold). Wrap and chill 30 min. (Fold #1)
Rotate dough 90°, roll again to 20×60 cm. Fold in thirds. Chill 30 min. (Fold #2)
Repeat once more for final fold. Chill overnight. (Fold #3)
4. Shaping (Morning – Day 2)
Roll dough into a 20×40 cm rectangle, about 4–5 mm thick.
Trim edges clean.
Cut into long triangles (~8–9 cm base × 20 cm tall).
Gently stretch each triangle, roll from base to tip, tuck tip underneath.
Place on parchment-lined tray.
5. Proofing
Cover loosely and let rise at room temp (22–25 °C) for 1.5–2 hours.
Ready when: visibly puffed (50–70% bigger), slightly jiggly when tray is shaken.
6. Baking
Preheat oven to 200 °C / 400 °F.
Brush croissants gently with egg wash.
Bake 15–18 min until deep golden brown.
Cool at least 10 min before eating.
Keep in paper bag/foil overnight.
Reheat at 175 °C / 350 °F for 5–8 min.
For longer storage → freeze cooled croissants, reheat from frozen at 175 °C / 350 °F for 8–10 min.
