Cooking in fireplaces & over campfires + campfires as fireplaces indoors

You can't cook anything in a fireplace (at least I can't) but you can cook all sorts of things like marshmallows, fish, hotdogs, etc. on the fire pit in the outdoor retreat mod (which is why I got it, funnily enough). Soups and stews would be kind of interesting. Bacon too. Then there's the wood stove they've got. I think it works the same as a normal stove though.

I could have sworn I saw a brick pizza oven somewhere. Was it a mod or was it part of a Sims 3 expansion pack? Still, I think that might be interesting. Imagine running a pizza parlor!
