1/2 cup butter 1 cup of grated cheese 1/4 cup grated parmesan cheese 1 teaspoon salt (plus extra for sprinkling on top - optional) 1/2 teaspoon garlic powder (optional) 1 tablespoon dried herbs 2 tablespoons milk
Combine everything, except the milk, in a food processor and pulse until it is looking like fine breadcrumbs. Add the milk to form a crumbly dough.
Turn out on to the bench and use the warmth of your hands to form a dough.
Roll out to approx. 3-4mm thick and with a fork, poke holes all over the dough. Sprinkle lightly with salt.
Cut in to desired shapes. I use a pizza cutter and just make chunky squares and rectangles. They get eaten quickly so you don't want to go to too much trouble.
Bake in a 200 degree (Celsius) oven until golden brown.
