seek10 said:since I can't take butter, I was using Ghee and didn't feel better with prescribed amount of coconut cream, I replaced it with more egg yoks. 1 cup ghee, 2.5 tsp xylitol, 12 egg yoks, some vanilla and lemon extract. While mixing, it didn't mix well and it wasn't smooth as custard, but it is more like solid cake with little granularity. But after freezing and melting in hot water and re mixing it, granularity disappears in refrigerator.
The water lost from turning butter to ghee is probably why you're not getting a smooth texture, and more yolks would make it stiffer as well. You could try replacing the butter with a 4:1 ratio of ghee to water, since butter is roughly 80% fat, though the solids from the butter are also removed (which I imagine would make the texture a little more firm) so it might be closer with just a bit less water.
