I’ve never tried to make this myself, but out of curiosity I wanted to try to make them, I remember them as tasty little treats.
4 tablespoons butter
2.5 dl flour
3/4 teaspoon salt
2 tablespoons cold water
Grate the cheese and combine everything in a food processor/blender except the water,. Blend utill the mixture is like coarse sand, then add the water 1 tablespoon at a time while blending, the dough wil start to come together.
Tip the dough out and wrap the dough and let it rest in the fridge for about half an hour.
Next step is to roll the dough thin and cut out little figures. I made a little fish shape cookie cutter from an old broken one, but you can make any shapes you want.
