- 250 g (9oz) unsalted butter, softened
- 125 g (4oz) caster sugar
- 1 medium egg yolk
- 250 g (9oz) plain flour, plus extra to dust
- 125 g (4oz) self-raising flour
- 24 tsp. (about 240g or 81/2oz) blackberry jam, or any dark jam
- tube of writing icing, optional
- Step 1
In a large bowl, beat butter and sugar together, then beat in egg yolk and vanilla. Stir in flours, using your hands if it’s too diffi cult to mix with a spoon. Gently knead dough until it comes together, wrap in clingfilm and chill for 15min.
- Step 2
Line 3 baking sheets with baking parchment. Split dough into thirds. On a lightly floured surface, roll out the first piece to about 3mm (1/8in) thick. Stamp out 24 x 5cm (2in) circles with a fluted cutter and put on to a baking sheet (re-roll trimmings as necessary). Chill. Repeat with second piece of dough, cutting out 24 more 5cm (2in) circles and putting on to another baking sheet. To cut out freehand keyholes in the second batch of circles to make lids: use a small knife to cut a circle about 1.5cm (¾in), then cut three straight edges for the bottom of the keyhole. Chill. Roll out the third piece of dough to 3mm (1/8in) thick and cut out 24 biscuits with a key-shaped cutter. Put on to a baking sheet and chill for 20min. Meanwhile, preheat oven to 180°C (160°C fan), mark 4.
- Step 3
Bake circles and lids for 7-8min until lightly golden and sandy to the touch. Remove from oven. Carefully spoon 1tsp jam on to each full circle, spread slightly, then put a lid on top and gently press. Return biscuits to the oven for 5min. Set aside to cool.
- Step 4
Bake key biscuits for 8-10min until lightly golden, then transfer to a wire rack to cool. Use writing icing to pipe patterns, if you like.
