As said, they won’t rise as much as a regular tea biscuit, but they also won’t be flat.u003cbr/u003eu003cbr/u003eWhen I want them taller, I shape the biscuits, then place the baking sheet into the fridge for 20 minutes before baking.u003cbr/u003eu003cbr/u003eOne very important thing to check is the oven’s temperature. If not preheated enough, you risk getting flat cookies. Also, always use extra cold butter, milk and sour cream, and do not handle the dough more than necessary.u003cbr/u003eu003cbr/u003eThis recipe uses baking powder and soda for the biscuits to rise.
