Heard someone on radio 4 (probably women's hour) a few months ago. He was talking about growing vegetables that are expensive to buy/unusual instead of growing common veg which are cheap to buy (eg potatoes)
He has written a book, about growing unusual veg and then includes recipes.
I have no idea who he is, just remembered him because I want to buy the book for my mum for christmas, can't find where I wrote it down, and too vague to google
