Cooking ponders.

So. While I was down visiting my father over Christmastide, I noticed that he had a jar of juniper berries in his spice rack. Unopened, but juniper berries. I asked Dad if I could have them, and he said I could, so now I have juniper berries.

So I have juniper berries, and am pondering at my recipe for wild-game style roast. Which looks quite good, though somewhat outside my normal experience of food, and like a lot of Polish food of my experience, very rich.

The roast is supposed to be marinated for two days. Mmm.

The marinade requires carrots (to which I am allergic) and celeriac (which I'm not sure if I'll be able to find). Anyone know of good substitutions for either of these? (teinedreugan thought maybe a small turnip for the carrot, perhaps, and I guess some celery might be usable for the celeriac if I can't find it, but I appeal to the more experienced.) alhandra, thoughts? Anyone else?
