If your biscuits are too dry and the dough doesn't come away from the sides of the bowl when mixing together the ingredients, then you can add more milk, one Tablespoon at a time until you reach the desired consistency. If your dough is too wet, add more flour. If you find that the dough is too wet to fold, you can add more flour, 1/4 cup at a time until you reach dough consistency. If the dough is just tacky, you add flour gently while folding over the dough on a heavily flour surface.
