I had a recipe for cheese scones (dry, not very cheesy) and one for cheese straws (mostly cheese, held together with willpower and a smattering of flour) and got the recipes mixed up. So then I tried mixing the two deliberately - worked out OK.
oven to gas 7 / 220 c. or thereabouts.
8oz flour (self-raising, or plain with 1 tsp baking powder)
3oz butter (if unsalted, add 1/2 tsp salt)
2oz hard cheese (cheddar, cantal)
cut up butter into flour etc, grate in cheese, work lightly to a breadcrumb-like consistency.
add 1 oz powdery parmesan, mix.
add 1/4 pint milk, mix with knife. flour hands, combine into a ball.
flour surface / rolling pin. roll out to c. 5mm thickness, cut to ritz-cracker size shapes.
cook for 10-12 minutes. cool on a rack. makes about 60 with one re-roll, and scraps.
optional extra: pizza glaze.
mix 1 tbsp ketchup with 1 tbsp milk to thin. brush on nibbles.
light sprinkle of grated cheese / parmesan, mixed herbs.
slices of black olive would probably also work but I didn’t think of that at the time.
