To bring butter to room temperature quicker, cut it into tablespoons or cubes. The more surface area you expose, the faster it will reach the desired temperature. The same method holds true when melting butter over the stove or in the microwave.
Whenever a recipe calls for ‘room temperature’ eggs, you don’t have to plan hours in advance. You can place your eggs in a bowl of lukewarm water for about five minutes to do the trick. It’s especially helpful for whipping eggs for desserts.
