If you're looking for British then it's pretty much just top-fruit (apples and pears) to take you into autumn. There's obviously no British fruit available in winter unless it's hothoused so you're looking at Spanish citrus or southern hemisphere stone fruit and grapes going forward.
Great website, thanks OneLittle Not really something to eat raw but rosehips are in season at the moment and great to cook with. I stuffed and baked some apples with them on the weekend. They were really lovely!
