Onion cut into strips and pour boiling water for 5 minutes. Drain the boiling water and cover with cold water. Add 1H. spoon of salt, 1ch. l. sugar, 1/2 tsp. black pepper, 1-2st. a spoon of vinegar. To allow to stand.

Heart boil (before cooking, I usually soak the heart for 2-3 hours, then boil about 3 hours, an hour before ready salted) and cut into strips.

With Luke drain the marinade. Add the onion to heart and mix. Fill mayonnaise + sour cream 50/50. Ready. Bon appetit!
