I followed most of the tips that commenters left behind, such as not adding water to the Ener-G Egg Replacer and only using half the juice from a lemon. Unfortunately, the batter was much too thick to blend in the blender & Mark had to add a tablespoon of water. The crust was also a challenge. One, I couldn't find any honey-free graham crackers. Two, the cookies I did choose were hard to spread over the pan. Oh, and we baked the "cheese" cake for the maximum time, at 35 minutes.
Next time, I think I'll try it at 30 minutes and maybe add water to half the "eggs". Oh, and maybe order some truly vegan graham crackers.
Here are the pics:
