In a large bowl whisk eggs. Blend in vegetable oil, orange juice, vanilla, lemon, almond and anise flavouring.
Sift the flour with the sugar and baking powder. Add the flour mixture to the egg mixture. The dough will probably be sticky. Add additional flour until the dough is no longer sticky and can be rolled.
Pull off a piece of dough about the size of a walnut. Roll it into a rope and shape it into a knot. Place finished knots 5cm apart on an ungreased baking tray.
Bake at 180 degrees C for 15 minutes. Bottoms should slightly brown.
Cool biscuits on a wire rack. If desired add an icing.
