Pastries, including quick breads such as pancakes, need something to help them rise during cooking. Called leavening agents, substances such as baking powder and baking soda create chemical reactions that cause the batter and dough to expand. Even though pancakes are cooked on a griddle rather than baked, baking powder works the same way by making them light and fluffy.
Common leavening agents include yeast, used in raised breads; baking soda; and baking powder. Yeast is an active organism that develops slowly in a warm moist environment. Baking powder and baking soda are chemically based substances that produce carbon dioxide in a wet medium, such as batter or dough. Baking soda needs an acid to function as a leavening agent, while baking powder already contains baking soda, along with cream of tartar, an acid, and cornstarch. Baking powder is the leavening agent of choice for pancakes, because the batter contains no acidic component that would activate plain baking soda.
Most pancake recipes are a combination of flour; a sweetener, such as sugar or honey; eggs; milk; and shortening, usually oil. They also typically include baking powder and a little salt to enhance the other flavors. Success depends on exact measurements, as too much flour makes pancakes too thick, dense and dry, while not enough makes the batter too runny. Eggs act as a binder to hold the other ingredients together, while milk provides the necessary moisture. Oil helps to cook the pancakes evenly from the inside.
Follow recipe instructions carefully, and use a wire whisk or fork to blend ingredients together just enough to eliminate most lumps. Batter can be kept in the refrigerator overnight and stirred again in the morning. If it has thickened, whisk in a few drops of milk to make it pourable. Pancakes are best cooked quickly on a hot oiled griddle set at about 350 to 375 degrees Fahrenheit. A drop of water should sizzle when it hits the surface of the pan or griddle. Pour or ladle out the batter in circles that measure roughly five inches in diameter and lift the edges of the pancakes with a spatula to check for doneness when air bubbles begin appearing across the top. Well-done pancakes should be a light golden-brown on both sides, which takes a four to five minutes.
Omitting the baking powder results in a batter that rises only slightly, but magically produces yet another confection -- the crepe. The same ingredients pancakes are also used to make crepes, with the exception of baking powder. Amounts of each ingredient may vary, but they produce a thinner more compact and chewier product that clearly reflects what happens when a leavening substance is omitted. Leaving baking powder out of the mix is what gives crepes their thin flexible consistency, making them ideal as breakfast or dessert choices. Roll them around a filling or layer them with fruit or a cream filling.
