Put all ingredients in a bowl and knead into a firm, but not too crumbly dough. Place in the refrigerator for 15 minutes to make the dough easier to work with.
Meanwhile preheat the oven to 200 ° C.
Then shape the dough into a roll (approx. 3 - 4 cm in diameter) by hand and cut the biscuits 1 cm apart, flatten them a little and place them on a baking sheet.
