I don't eat dairy products or grains but I manage to make a really good tasting lemon custard with just whole eggs, lemon juice and non-caloric sweeteners. Great stuff! I've figured out I can make this with my water-bath and cook it for 30-40 minutes at 155 degrees and it turns out nice. However, I'd like to make other flavors other than citrus but I am having a really tough time doing it. I guess the acid makes the eggs thicken at a lower temperature. I think maybe the issue is I'm using yolks and whites and they coagulate at different temperatures, maybe the acid removes that variability. I'm just curious if anyone has any suggestions? 155 seemed too low. I tried cooking it for 60-90 minutes and couldn't get it firm enough. I've tried slightly higher temps and I either overshoot or undershoot. Anyway, my goal is to only use eggs, no dairy, no flour. A little xanthan gum, or similar, is okay though. Any suggestions?
