These tips will help you turn out great biscuits. Keeping the fats cold gives the biscuits flakiness. Handling the dough as little as possible ensures the biscuits will be tender. Some recipes call for gathering and rerolling scraps, which can lead to tough biscuits; cutting rectangular biscuits is a clever way to avoid this, as rectangles leave no scraps. Cutting the biscuits with a straight-down motion produces an even shape, and baking them at high heat results in biscuits that rise high and brown handsomely.
