Using a food processor simplifies the dough-making process, but it isn't strictly necessary. If you don't have one, a stand mixer or even a mixing bowl and a spoon will suffice. A pastry blender also helps for cutting butter into the dough, but you can use 2 knives instead. If you're baking shaped biscuits, gather a rolling pin and a biscuit cutter. If you're making drop biscuits, you'll need an extra spoon. Grab a large baking sheet and have it nearby.
