The dish gained popularity in postwar Poland as a way for families to create a filling, comforting meal using basic, available ingredients like milk and eggs. In some regions, particularly among families repatriated from western Ukraine (such as Lviv), it was served with rice or sweet rolls to make it more substantial.

Milk thickened with egg yolks and sweetened with sugar.

Often infused with real vanilla or vanilla sugar.

(literally "nothing soup") is a traditional Polish milk soup that is a classic example of a "poor man's" or frugal dish, often associated with childhood and post-WWII culinary history.
