Winter shortage of veg

On the back of the reported shortages, a member of the government suggested yesterday that Turnips could be a suitable alternative whilst tomatoes and cucumbers are in short supply. It seems that what they were trying to convey was, that we should be eating seasonal UK produce and supporting our own farmers. Whilst I agree with that sentiment, they might have done better suggesting carrots, not turnips. (Reminds me of Baldrick!). https://www.youtube.com/watch?v=jD2iYSKHHzo

I've lost count of the number of seed retailers who are promoting turnip seeds today.
How many of us grow turnips? I've tried several times but can't say they are my favourite veg - maybe because I don't grow them very well and they end up the size of large radish.
