Should pancake batter rest before using?

Yes, it is recommended to let pancake batter rest before using it. Here are a few reasons why:

1. Gluten Relaxation: Allowing the batter to rest gives the gluten in the flour time to relax and hydrate. This results in a more tender and fluffy pancake. When gluten is overworked, it can make the pancakes tough and dense.

2. Ingredient Hydration: Resting the batter allows the dry ingredients, such as flour and baking powder, to fully absorb the liquids, like milk and eggs. Proper hydration ensures that the ingredients are evenly distributed throughout the batter, contributing to a consistent texture and flavor.

3. Flavor Development: Letting the batter rest can enhance the flavor by allowing the ingredients to mingle and develop their flavors. Some recipes even suggest adding ingredients like vanilla extract or spices to the batter and letting it sit for a while to infuse more flavor.

4. Air Incorporation: If you whip the egg whites separately and fold them into the batter just before cooking, resting the batter helps retain the incorporated air. This contributes to lighter and fluffier pancakes.

5. Consistency Check: Letting the batter rest gives you a chance to check its consistency and make adjustments if needed. If the batter appears too thick, you can add a little extra liquid, and if it's too thin, you can add some more flour.

The resting time for pancake batter can vary from recipe to recipe, but it's usually recommended to let it rest for at least 5-10 minutes, and some recipes may suggest up to 30 minutes or even overnight. Always follow the specific instructions provided in the recipe for the best results.
