Description

Fluffy sourdough croissants with a rich, tangy flavor and delicate buttery layers, combining traditional lamination with natural fermentation.


Ingredients

  • 500 g all-purpose flour
  • 100 g active sourdough starter
  • 250 ml whole milk, slightly warm
  • 50 g granulated sugar
  • 10 g salt
  • 250 g unsalted butter, cold (for laminating)
  • 1 large egg (for egg wash)

Instructions

  1. In a large bowl, mix flour, sugar, and salt.
  2. Add sourdough starter and warm milk, mixing until a rough dough forms.
  3. Knead until smooth and elastic.
  4. Cover and let rest at room temperature for 4–6 hours until slightly puffed.
  5. Refrigerate dough overnight.
  6. Prepare butter block by flattening cold butter between parchment into a rectangle.
  7. Roll out chilled dough, place butter in the center, and fold dough over it.
  8. Roll out dough and perform 3 folds (turns), chilling for 30–45 minutes between each.
  9. After final fold, roll dough into a large rectangle and cut into triangles.
  10. Roll each triangle into croissant shapes and place on a baking tray.
  11. Proof at room temperature for 4–6 hours until puffy and slightly jiggly.
  12. Brush with egg wash.
  13. Bake at 200°C (390°F) for 18–22 minutes until golden brown.

Notes

  • Use active sourdough starter for best rise and texture.
  • Keep dough and butter cold during lamination to prevent butter leakage.
  • Chill between folds to maintain distinct layers.
  • Avoid microwaving when reheating to preserve flakiness.
  • Croissants should jiggle slightly when properly proofed.
