Allow jam to substitute berries in recipes

[HarrowMinded]

I imagine we're probably going to have a recipe involving jam at some point, but I would love if we could use jam in places where berries are normally required in recipes. Things like porridge, meat stew, or pies.

It just seems strange to me that the only usage for jam is to eat a bowl of it, rather than adding it to other things. And I can't think of a reason why it wouldn't be sound logic to put it in the same recipes in place of full berries, I suppose fruit pies not withstanding.

And let us put it on bread for goodness sake!

So you already have peanuts in game, you can bake bread,  add a recipe for peanut butt and jam sandwiches.

Heck, you have pigs, you can make cheese, ham and cheese sandwhiches.

OMG I'M A GENIOUS!
