There aren't a great deal of food words beginning with the tail-end letters of the alphabet, so, in this final article in the series, I'm going to cover U, V, W, X, Y, Z. I can think of ten foods beginning with these letters: veal, venison, walnuts, watercress, watermelon, wheat, yams, yofu, yoghurt and zucchini, and I'll discuss five of these in detail.
