Drying milk. Milk can be gather in Olivia Town, there is a bunch of cows you can milk.

If you don't want to gather milk by yourself, you can rent a fence (the same used to grow plants) and put haystack (they count as 4 plants in space), the haystack attracts cows and you gather them like they were plants, and give you milk, meat, etc.

При высушивании молока - получаешь от 1 до 4 единиц сыра, а не 1.
