The first step of most recipes is to preheat the oven to the specified baking temperature suggested by the recipe. When you preheat the oven, the goal is to warm the oven as a lot as the temperature you need to bake at. This is the rationale why you must give your oven loads of time to preheat, earlier than you start baking. You wish to avoid exposing your baked goods to that blast of warmth from the heating components, which is unpredictable at greatest.
