Kasukas, AKA "Fur coat salad"

This is another recipe from my mother-in-law, and another one where, like monkey gland sauce, you shouldn't mind the name. Use only the finest fur coats in your salad. Since it's Estonian, you should probably use bear or fox fur. It gives it a real Baltic taste.

This makes plenty. It's worth the effort, trust me...

2–3 potatoes, boiled and grated
3 large carrots, boiled and grated
2 big apples, grated
5 eggs, hard boiled. After boiling, keep the yolks and the whites separate. Chop the whites up finely.
2–3 pickled herring fillets (I find the German variant to be a bit sweet for my liking, so if you can, use a Baltic brand), finely chopped
1 or 2 smallish onions
400 g beetroot, boiled and grated
300–400 g mayonnaise
300–400 g sour cream

This is a layered salad, but it might be a bit bland, so read to the end of the recipe. The order is as follows:

Grated potato, mayo, herring, sour cream, onion, mayo, egg whites, sour cream, carrot, mayo, apple, sour cream, beetroot, sour cream, in that order. You can leave out one or two layers of mayo or sour cream, but make sure to add one or the other on top.

Add seasoning between some layers, and leave to sit in the fridge overnight. Before serving, crumble the egg yolks over the top. Enjoy.
