Back to the Hungarian post 

100 g grated parmesan

100 g grated gouda cheese

100 g flour

80 g butter

small teaspoon of baking powder

I started the preparations with doubling the original recipe's amounts, as 16 pieces are just nothing for kids, not to mention adults :). Nigella used Cheddar, but I had other types of cheese at home, so to compensate the dryness of the parmesan (which provided a very characteristic taste), I used more butter. It was not easy to get the dough to its required consistency, I had to work the ingredients together for quite a long time. Then I put it in the fridge for 15 minutes, packed in clingfilm, then rolled it out to about 3 mm thickness and cut out forms with cookie cutters. Nigella used a foot-shaped cutter, I had hands :). Bake them in an oven preheated to 200 C for about 12 minutes. This amount adds up to two baking sheets, but lasts only for minutes :).
