We Should Bake with Room Temperature Ingredients: Truth or Fiction
When ingredients are at room temperature, eggs, butter, and dairy products form an emulsion which traps air. While baking in the oven, the trapped air expands and produces a fluffy baked good.
Room temperature ingredients bond together easily since they are warmer. This creates a seamless and even textured batter. When you have a smooth batter, you have a uniformly textured baked good. Cold ingredients do not incorporate together as easily.
