1 box of soft silken tofu
2 tablespoons of water
Blend together till very smooth. Use 1/4 cup for every egg you wish to replace.
I lived a 6000 feet, rather high altitude, and found that using this recipe for eggs in any baking product worked perfectly.
In baking, eggs provide the protein that supports the risen cellulose structure. Tofu is high protein and will do the same thing.
