Terry, try some carrots kept in sand. Dry the sand off in the summer box it and put it in the shed then just lay the carrots not touching in a layer of sand and cover and repeat till the box is full. More taste when you take them out than frozen carrots. The same can be done with beetroot and parsnip.

I will give that a try Allan. I have got a few beets in the shed in compost which I have not checked as an experiment . Sand sounds a good plan plus the council are all ways leaving bags of it laying around
