Unless you have a backyard chicken coop and plenty of eggs this tip will save you money.
Instead of using eggs in a recipe, I substitute 1 TBL cornstarch and 3 TBL water per egg. To date I have made several different kinds of cookies, pancakes, and muffins, all calling for anywhere between 2-8 eggs, with no detectable difference!!
I buy our cornstarch by the 5 pound bag at our local Cash and Carry. Last time I was there (APR 2011), I paid $4.40 for the bag.
Try it and be sure to post a comment on how it worked with your baked goodie!!
