Hi Eva, That’s awesome that you are helping your son this way. I haven’t tried this with other tools, but you could probably use either the blender or the food processor. The key is to pulse in step 5, not just constantly blend, so that the whites don’t fully break down. Other than that, it should be pretty similar. As for the yolks, if you don’t want to make creme brulee, I usually just put a couple extras into an omelet (or breakfast casserole, or any other dish requiring cooked eggs) mixed with whole eggs.
Maya, this is a beautiful looking bread. I’m going to try it, but before I do, I’d like to know if you have ever tried doubling the recipe. It seems that it would work–based on the fact that my almond flour bread that I have made for years uses 3 1/4 cups flour, and turns out pretty well. (I’m pretty content with my recipe, but admit that yours looks better due to the whiteness and it appears to have more air bubbles, indicating it’s probably lighter.) If I don’t hear from you, I’ll probably go ahead and double it, and use a 9×5 pan–wish me luck.
