You are already talking about bread.

Peasant bread - rusted, on the ferment, is stored for about a week. White - a couple of days maximum. Don’t confuse the fuck with the finger. These are two different products with different technologies. The closest to the "tom" bread is Borodin, and then in some bread plants. And yes, it is easily stored for up to a week. Many, speaking of "peasant bread", imagine lush wheat caravays, rather than sour dark patches with strawberries.
