In a bigger bowl put all the dry ingredients plus the egg yolks. Mix well with a wooden spoon. It will be extremely dry.
Beat egg whites, honey and apple cider vinegar until stiff.
Now mix the egg white mass into the flour mix carefully. The dry flour mix will absorb all well and become a dump bread mix.
Now put the whole bread mix into a 18 inch loaf pan and put it into the preheated oven.
After 20 minutes turn the oven down to 150°C/300°F
Turn the oven off when the toothpick prove comes out clean. Let it stay another 10 minutes in the oven with the door open and then take the bread out of the oven and the loaf pan and let it cool on a cooling rack.
Instead of the almond flour you can use any other nut flour except coconut flour as the texture is very different.
Who doesn't like apple cider vinegar can use lemon juice.
Note: any variation of ingredients give another taste.
