Jos offers a fairly nice production chain, and especially interesting in terms of raw materials: the production of Donuts on Farming Simulator 22.
A classic building (restaurant) to place on the map, just supply it with flour, sugar, milk, egg, butter, strawberry and chocolate. As an outlet, 3 choices of donuts are available: with sugar, with strawberry icing, or chocolate topping. The idea is nice, will appeal to the greediest, and requires a lot of work upstream.
