In celebration of the new sheep cheeses, I would like to suggest an alternative source of rennet, primarly for casual players/hermits who dont have the time or resources to manage a whole farm of animals.
historically, rennet comes from animals, although alternatives are available albeit not as effective as animal stomachs. one such alternative is nettle rennet. As stinging nettle are already implemented into the game, perhaps making a crafting recipe with nettle to make rennet would be acceptable. Of course, this couldn't be a replacement for suckling's maw, so there would have to be relatively ineffecient compared to the original method. perhaps 5-10 nettles, .5-1l of vinegar along with a tertiary component.
Again, my main idea here is that casual/hermit players will be able to at least play with the cheese industry without having to first create a whole farm of animals.
please feel free to leave comments or suggestions.
