The dough is quite easy but preparation may take time and make sure to use small cookie shapers/cutters.
Dough (2 baking sheets):
150 g flour
100 g butter
100 g cheese (mixed grinded cheddar or gouda and parmigiano reggiano)
a good pinch salt - amount depends on the cheese
pinch sweet chilli powder so called Paprika
smaller pinch smoked chilli powder
1 egg yolk
1 tablespoon milk
1 egg yolk, slightly beaten
seeds (white sesame, cumin, nigella seeds/black cumin)
First cut butter into small cubes. Mix cheese with egg yolk, add butter, spices, salt, flour, milk and kneat into a dough (by hands only no kitchen engine please). If the dough is way too dry and crumbly add a little more milk. Work quickly and store the dough in the fridge for about 30 minutes.
Roll the dough over a lightly floured baking board and cut very small cookies, roll a rather thin layer, the cookies will rise a bit. If you work in two batches make sure to store half of the dough in the fridge until you need it again.
I always use pastry shapers I bought for small money on an antique market, they are over 100+ years old but it would be a waste not to use them. So maybe you don't have the same shapes but it doesn't matter. I just would not want to use shapers for easter or christmas (laugh), so I prefere rectangle shapes, circles, fish, mushroom and a heart.
Put the cookies or crackers on a baking sheet (use parchment paper or a duration baking foil), pinch the cookies lightly with a fork (just 2x each cooky), baste with some egg wash and sprinkle with seeds.
Bake for about 10 -12 minutes at 180 degree Celsius or until golden. Lovely cheesy smell...
Here we are: a small heart
