- Day 1: Make the dough. Mix flour, salt, sugar, yeast, milk, and water until a shaggy dough forms. Knead briefly until relatively smooth. Shape into a rectangle, wrap in plastic, and chill for at least 1 hour or overnight.
- Prepare the butter block. Place cold butter between parchment paper. Pound and roll into a 7-inch square. Chill until pliable but cool.
- Laminate the dough. On a floured surface, roll the chilled dough into a rectangle. Place the butter block in the center and fold the dough over it like an envelope, sealing edges completely.
- Perform the first fold. Turn dough 90 degrees. Roll into a long rectangle. Fold the bottom third up and the top third down over it (a letter fold). Wrap, mark with one fingerprint, and chill for 45-60 minutes.
- Repeat the rolling and letter folding process two more times, chilling between each fold, for a total of three folds. After the final fold, wrap dough tightly and refrigerate overnight.
- Day 2: Make the frangipane. Cream softened butter and powdered sugar. Beat in egg, almond extract, and salt. Mix in almond flour until smooth. Set aside.
- Make simple syrup. Heat equal parts sugar and water in a pan until dissolved. Let cool.
- Shape the croissants. Roll the chilled dough into a large rectangle, about 1/4-inch thick. Trim edges. Cut into triangles.
- Place a tablespoon of frangipane near the wide base of each triangle. Roll from base to tip, curving ends inward to form a crescent. Place on a parchment-lined baking sheet.
- Proof the croissants. Let them rise in a draft-free, slightly warm place until puffy and jiggly, about 1.5-2 hours. Preheat oven to 200°C (400°F) towards the end.
- Brush proofed croissants gently with egg wash. Sprinkle generously with sliced almonds.
- Bake for 18-20 minutes, or until deep golden brown and hollow-sounding when tapped.
- Immediately out of the oven, brush croissants lightly with the cooled simple syrup. Let cool on a wire rack before serving.
Notes
For best results, keep everything cool during lamination; if butter softens, chill dough immediately. Use high-fat European butter for optimal flakiness. Scraps from trimming can be used to make cookies. Croissants are best eaten the day they are made. Reheat leftovers in a toaster oven to re-crisp. Ensure yeast is fresh for proper proofing. A little frangipane leakage is normal and delicious.
