I made this the other day, it is in German but I think it does not matter as you can see clearly what I do.

Eggyolks (you can let a bit eggwhite in too, I sometimes do, about 1 eggwhite), wild raw honey. Whisk until foamy. Add berries, I use wild berries only.
If you like you can add raw unsalted butter in the end, to the foam. This is very delicious too. The butter have to be soft and use about 3 teaspoons / 4 yolks added in parts as you whisk - at the end.

Eierschaum teil 2This is great for non-raw eaters too! My hubby eats SAD and he loves this! He just like it more sweet so I add more honey for him. Very nourishing. I guess great for kids too! There will be zero "yuck"factor with this, as it often happends for people with raw eggs eaten plain.
