People like to think of it as peasant food but that's exactly why it is so good. It's simple, hearty good food. It'll fill you up. It uses generally local spices and ingredients. It usually lasts decently long since it involves a lot of the time sourdough and fermenting like with sauerkraut. A good example is finnish food, or german food. Polish food is also excellent. Rye is another staple and is in my opinion the supreme grain (together with barley, fuck wheat) and proper rye sourdough thick malty bread is the most delicious bread in the entire world. It pwns wheat bread.
