If making your own spice, grind all the ingredients together in a pestle and mortar or spice mill. Feel free to change the proportions to your own taste.
Mix together the flour, almonds, baking powder, baking soda, salt and spices in a bowl. Set aside.
In a stand mixer, cream the butter and sugar until light and fluffy. Add egg and beat together.
Slow down the mixer and gradually add the contents of the flour bowl.
On a clean surface, pat the dough into a large flat circle, cover with clingfilm and leave in the fridge overnight.
Preheat the oven to 170ºC and prepare a couple of flat baking trays lined with a Silpat or parchment.
Scatter flour onto a clean surface and roll out the dough to 1cm thick.
Cut out sections to the size of the mould.
Rub rice flour into the interior of the mould.
Press a section of the dough into the mould then using a palette knife or a sharp knife, run it flush along the mould, cutting off the excess dough.
Turn over the mould and carefully but firmly tap out the biscuit against the counter top.
Place each biscuit onto the flat baking tray as you go.
Rub flour into the wooden mould each time.
Gather together the scraps and continue to make biscuits.
Place the baking trays into the fridge and leave to chill for at least half an hour. This step is important as otherwise the biscuits to puff up too much and lose their shape.
Bake for ten minutes.
Remove from the oven and let the biscuits cool completely in their trays.
For extra crunchy biscuits (my preference, especially for optimum dunking) put the biscuits back in the oven to bake a second time for 3-5 minutes. After all, the word biscuit is French for ‘twice baked’.
Use a sieve or tea strainer to sift icing sugar over the biscuits.
To further highlight the pattern from the mould, gently rub or brush the icing sugar into the grooves of the biscuit. Serve with coffee or liqueur.
