Sir: I, too, have a copy of Delia Smith's Frugal Food (letter, 19 January). Sadly, the price of such items as whiting, shoulder of lamb and even streaky bacon make them a rare treat for those on a tight budget. Others, such as mutton, are things of blessed memory only. And as for oxtail - think BSE. I also suspect that Ms Smith might be just a soupcon embarrassed by some of the recipes: pizza with cream cheese, for example. Still, who would not embarrassed by youthful follies?
