Every person who's been lucky enough to taste some of these, always asks for the recipe. Lady M did exactly that when we first encountered them at artist Simon Fletcher's house; his wife Julie is a superb cook. I suppose I really ought to call them 'Julie's Amazing Parmesan Biscuits'.
I think Lady M's ingredients are as follows: 100gms each of butter, flour, and freshly grated parmesan (don't skimp on quality), and an egg yolk; plus some chilli powder (quarter tsp) and a few cumin seeds (1 tsp).
Wizz up to form a ball, refrigerate for a while, then roll out and cut into small biscuit shapes. Don't over bake (about 10 mins; keep watching).
Other than the first four ingredients the rest is according to taste. Don't add salt.
The biscuits are delicate, simple to make, slightly spicy, and totally delicious; perfect to offer to guests with a glass of rouge.
