125g butter
160ml sugar
1 egg, separated
30ml milk
5ml vanilla
250ml flour
83ml cocoa powder, sifted
1,2ml salt
250ml pistachio, finely chopped
80g nut butter chocolate, chopped
15ml cocoa butter
Preheat your oven to 180℃ and line a baking sheet with baking paper.
Add the butter and sugar to the bowl of a stand mixer fitted with the paddle attachment and cream together.
Add the egg yolk, milk and vanilla and mix together.
Stir in the flour, cocoa powder and salt until combined.
Wrap the dough in plastic wrap and chill in the refrigerator for at least an hour.
Add the egg white to a small bowl and whisk until frothy.
Chop the pistachio finely (I do mine in a food processor) and place it in a shallow bowl.
Scoop up about 15ml of dough and roll it into small balls.
Now roll each ball in the egg white and then in the chopped pistachio.
Place the balls on the prepared baking sheet.
Use the back of a 2,5ml measuring spoon to make an indentation in the centre of each dough ball.
Bake the biscuits for 12 minutes.
Remove the baking sheet from the oven and immediately re-press the indentations you made. Set aside to cool completely.
Add the chocolate and cocoa butter to a heatproof bowl set over a saucepan of simmering water and allow to melt.
Stir every now and then until smooth and glossy.
Remove from the heat and stand the bowl for about 30 minutes.
Spoon the chocolate into the indent in each biscuit and set aside to allow the chocolate to set – preferably overnight.
Makes about 25 biscuits.
