Lemon stars

Put all the curd ingredients in a saucepan over a low heat, stirring constantly, until the mixture thickens, about 5 mins. To check if it’s ready, dip a wooden spoon in and blow on it gently. If a wave-like pattern forms, remove from the heat and sieve into a bowl. It will thicken more as it cools. Tip into a sterilised jar and leave to cool completely.

Beat the butter and sugar together in a large bowl. Mix in the egg yolks and the vanilla extract, then add the flour, almonds and a pinch of salt. Work everything into a smooth dough with your hands, then wrap and put in the fridge for 1 hr.

Heat the oven to 170C/150C fan/ gas 3. Roll out the dough on a floured surface to a thickness of 4mm. Press out stars using the larger cutter, then make a hole in the middle of half of the biscuits with the smaller star cutter. Re-roll the excess, making sure you don’t overwork the pastry, and stamp out more biscuits. Put the biscuits on a baking sheet lined with baking parchment, and bake for 10 mins until golden. Leave to cool on the baking sheet.

Spread the lemon curd on the biscuits without a hole, and put a biscuit with a hole on top of each one. Dust the biscuits with icing sugar. Will keep in an airtight container for up to three days.
