I like most of the usual suspects although beetroot is not at the top of my must have list. I don't like celeriac (although it has turned up in my veg box when I don't check what's going to be in there!). Nobody seems to know whether, if you are allergic to celery, you are allergic to celeriac too. I have had it once or twice and it seems to have no real effect except to make me feel rather itchy, whereas celery makes me extremely itchy. Not life-threatening like bananas, fish, shellfish, and tap water.
I have suddenly decided to like potatoes. I never used to eat them hardly at all except as jacket potatoes, chips or in curries, but lately I've started eating them more often. My favourite way of cooking them is to do them as microwave jacket potatoes and then chop them up and fry them lightly.
