What - you've never had them before?
You're missing a treat. Seriously.
To find a full set of instructions, head over to the Hambly blog. Or, if you're here for my more or less idiot-proof biscuit/cookie recipe (delete as culturally appropriate), behold:
PLAIN AND SIMPLE VANILLA BISCUITS
175g sugar (I used brown, but caster is probably better here)
Pinch of salt
2 tsp vanilla extract
300g plain flour
:: Cream together butter and sugar.
:: Beat in the egg, salt and vanilla essence.
:: Add the flour to form a smooth, soft dough.
:: Place in the fridge for 1-2 hours to chill.
:: Roll out on a flat, floured surface, then follow the cutting out/inserting stick instructions here.
:: Place on a lightly greased or good non-stick baking sheet.
:: Heat oven to 180ºC (160ºC fan oven / 350ºF / gas mark 4) and bake for around 10 minutes, until the edges are just starting to turn light brown.
Replace the vanilla with almond extract for a marzipan-ish taste, or with a few drops of orange oil if citrus is your thing.
