In the past, cheese was usually packed in black wax. Nowadays this is rarely done.
It is found either in foil packaging (such a cheese can not breathe) or wrapped in greased cheese wraps, which allow the cheese to breathe and at the same time protect it from dirt getting into it.
Sunflower halva is popular in the former Soviet Union, Bulgaria, and Romania.
It’s made with roasted and ground sunflower seeds, instead of tahini. In the 1990s, Ukrainians produced around 4000/5000 tons of sunflower halva annually.
