Mix all dry ingredients in a bowl. Mix the liquid ingredients in a second bowl and add to the dry ingredients. Knead everything into a dough. The dough is slightly oily and crumbly.
Shape the dough into balls the size of a table tennis ball, place on a tray and flatten slightly. Don`t sit too close to each other. Bake the biscuits for 8-10 minutes, then they are just a little bit soft in the middle. If you like it crispy, leave it in the oven for a few minutes longer. Take the biscuits out of the oven and leave them on the baking sheet for another two minutes. Let cool on a wire rack.
