Food in the USSR was actually more than food. After starving post-war years, this opportunity - not only to find food but to please a family and guests with something tasty and creative - turned home cooking into art. Yes, it's true that range of products choice was scanty. But in USSR was something that hardly can be explained to those who live in the world of abundance - "art to find scarce goods".
All those who were in trade, public catering, food industry carried out so much that it was enough for their family, all friends and relatives. A so-called "backscratching" principle was rather popular between factories and collective farms. So they preserved different vegetables for winter.
