Mark Hix says you should borrow some sugar beet from a friendly farmer
Why don't we regard sugar beet as a vegetable like swede or turnips or parsnips or even its close relative the beetroot?
It is commonly grown as a rotation crop in conjunction with wheat, barley and pulses, used to return organic matter into the soil and prevent the build-up of disease. It’s grown in some areas for the production of sugar but not commonly used in the kitchen. Heaven knows why, it’s great. It has a natural sweetness and a nice firm flesh, making it a very versatile vegetable indeed.
I often find myself standing in a field of the stuff whilst shooting and a few years back I popped a few heads into my cartridge bag and took them home to experiment with. I made a delicious pickle using Indian spices, I pickled some more in cider vinegar and roasted the rest like you would swede and parsnip.
I’ve asked some of our rural supplies to source it for the restaurants and it now makes its way onto the menus in various forms. It’s particularly good with wild or tame duck, or as a chutney to serve with cheese. You won't find it in the shops but you may well have a country residence with a nearby farmer – I'm sure they won't mind you borrowing a head or two to cook with.
