200 g dark brown sugar or Belgian cassonade (1 cup)
150 g soft unsalted butter (10 tbsp)
1/2 tsp baking soda
1/4 tsp salt
1 tbsp ground cinnamon
1/2 tsp each ground nutmeg, cloves and ginger
1/4 tsp each ground cardamom and white pepper
1 egg
1 tbsp milk
How to make it
Dough (10 min, then overnight): Beat the butter and sugar until combined. Mix in the egg and milk, then the flour, soda, salt and all the spices to a firm dough. Wrap and refrigerate overnight; the spices bloom.
Roll (10 min): Roll to 3 mm thick between parchment. Press with a speculoos mould or stamp, or cut rectangles and mark with a fork.
Chill (15 min): Chill the cut biscuits on the tray 15 minutes so the pattern stays sharp.
Bake (12 to 14 min): Bake at 170C (340F) for 12 to 14 minutes, until deep brown at the edges. They crisp as they cool.
Tips
Dark brown sugar or cassonade gives the caramel taste.
Crush leftovers into a pie crust or over ice cream.
