Kogiel Mogiel (a fluffy egg desert from childhd)
Whisk the egg yolk, sugar and vanilla sugar in a glass until very creamy, slowly add the lemon juice while mixing.
Add the fluffy egg whites spoon-by-spoon in to the yolk cream until all the fluff is mixed and now you have only a fluffy yummy deliciousness in the glass.
The best eggs for this are of course from the farm, I buy mine from my local farmer, not from the store. The yolks are orange and healthy. I see the chickens run and peck around the farm looking healthy and happy, every time I go there. They also taste so much better, than store bought. They taste like the eggs from my childhood.
Try to find a farmer in your area and take your kids for a weekend drive. They will love it.
