The Recipe
What you'll need
- Mixing bowl
- Hand or stand mixer
- Baking sheet
- Parchment paper
- Pastry brush
- Sharp knife
Ingredients
- 225g (1 cup) unsalted butter, softened
- 150g (1¼ cups) confectioners' sugar
- 2 egg yolks (whites reserved for the edges)
- 1 tsp vanilla extract
- 300g (2½ cups) all-purpose flour
- ¼ tsp salt
- Zest of 1 lemon or orange (optional)
- Coarse or turbinado sugar, for the edges
Instructions
-
Preparation Line a baking sheet with parchment paper.
-
Mix the dough Cream softened butter and sugar on medium speed until light and fluffy. Add egg yolks and vanilla, mixing until incorporated. Add optional citrus zest. Sift in flour and salt, mixing on low speed just until the dough comes together.
-
Chill Divide the dough in two and roll each half into a log about 4cm (1½ inches) across. Wrap and refrigerate for at least 1 hour, until firm.
-
Sugar the edges Lightly beat the reserved egg whites. Brush each chilled log all over with egg white, then roll it in coarse sugar to coat — this becomes the crackly rim on every slice.
-
Slice Preheat the oven to 180°C (350°F). Slice the logs into rounds about 1cm (⅜ inch) thick and arrange 2cm apart on the prepared baking sheet.
-
Bake Bake for 12–15 minutes until the edges just begin to turn golden. Cool on the sheet for 2 minutes, then transfer to a wire rack.
Tips & Notes
- Chill the sliced cookies on the baking sheet for 15 minutes before baking for cleaner edges
- The logs keep well — refrigerate up to 3 days or freeze up to a month, and slice straight from cold
- For plain sablés, skip the egg-white-and-sugar step and slice the logs as they are
- Store in an airtight container at room temperature for up to one week
