Mary, here's a good starch-based egg replacer, which works well in yeast bread: For 1 large egg, whisk together the following: 1 1/2 teaspoons tapioca starch 1 1/2 teaspoons potato starch 1/4 teaspoon baking powder 1/8 teaspoon (a big pinch) xanthan gum 3 tablespoons cold water Let sit for 10 minutes, then whisk until it appears lighter; the mixture will increase in volume a bit. Good luck - PJH
