What Can I Use as an Egg Substitute When Baking Corn Bread?by Fred Decker
Some ingredients are relatively easy to substitute in baking, while others are relatively difficult. One of the hardest to replace is eggs, because they do so many things in a recipe. Still, if you have a vegan in the house or have a kid with egg allergies -- or if you've just plain run out of eggs -- there are ways to cope. It is easiest when you're baking things like cornbread, which have a relatively coarse texture.
You probably don't think of it that way, but your cupboard full of baking ingredients is really a chemistry set. Most ingredients play a complicated role in the chemistry of your baked goods -- and eggs are a leading example. The proteins in the egg whites help give your baked goods structure, cooperating with the gluten in your flour to trap air and help the batter rise. The fat in egg yolks helps soften the crumb and enrich the flavor, and they contain emulsifiers that help the other ingredients mix better. Substituting for such a versatile ingredient is a tall order.
If you keep flax seed in your home for baking, you already have one of the most functional egg substitutes. To replace the eggs in your recipe, spoon flax seeds into your spice grinder and pulverize them. For every egg your corn bread recipe calls for, mix two tablespoons of the fresh-ground flax with three tablespoons of water and let the mixture sit for a few minutes while you measure the other ingredients. The flax will gel slightly, and simulate the texture of the egg in your cornbread. Flax doesn't help your cornbread rise, so add an extra 1/8 of a teaspoon of baking powder to compensate.
They're not always suitable because of the flavors they add, but you can also use fruit purees as an egg substitute. Use three tablespoons of mashed banana or avocado, or the same amount of applesauce or pumpkin puree, in place of each egg. These add richness and flavor to your cornbread, but you and your kids have to be comfortable with their flavors. Usually, you'll need an extra quarter-teaspoon of baking powder to compensate for their lack of leavening power.
If you're working on a permanent substitution, keeping commercial egg replacers on hand is probably your best bet. Some brands use liquid or powdered egg whites, so read the label carefully if you're accommodating a vegan or an egg allergy. Others use a variety of gelling ingredients, such as xanthan gum or guar gum, to give the finished product a suitable texture. You might find the crumb of your baked goods is tougher when you use egg substitutes, but adding a little extra fat will compensate for that.
If you just need a one-time replacement and it doesn't have to be vegetarian-friendly, you probably have a couple of other replacements in your cupboard and fridge. Gelatin makes a serviceable emergency replacement, providing a similar quantity of protein. For each egg soften a tablespoon of unflavored gelatin in one of cold water, then add two tablespoons of cold water and whisk it vigorously until it froths and add it to your cornbread. Alternatively, add three tablespoons of mayonnaise to your cornbread for each egg the recipe requires.
