I used to be o have a vast collection of cookery books but when my ex and I split I just kept my favourites and left him with most of them, including Jamie Oliver, Keith Floyd and Nigel Slater books.
I still have
Readers Digest Cookery Year
Readers Digest Guide to Creative Cooking both well used over the years
Delia's complete Illustrated Cookery Course
Ditto her Summer, Winter and Christmas books. I have to say though That I've found her cooking times too long.
Jocelyn Dimbleby's various little books all have something delicious.
The Milk Marketing Board Dairy Cookbook
Marguerite Patten's Feeding the Nation, just out of curiosity when she was regularly featured on Chris Evans afternoon show.
Levi Roots Carribean Cooking
John Tovey Country Weekends. When I used to entertain!
Nigella, How to Eat
Bill Grainger Holiday, hardly used
Betty's cookery School, recreates the recipes from Betty's Tea Shop in Harrogate
The Archers Cookbook both of these are really good.
The Life and Cuisine of Elvis Presley. Gut busting and horribly tempting recipes if you just want to get fat and have a heart attack!
I rarely use any if them these days as the Internet has everything and that's where I go for Mary Berry, but just once in a while it's good to dip into an old favourite.
I almost forgot the best Asian cookbook ever.
The All Asian Cookbook by Jackie Passmore. Very labour intensive but with fabulous results. I remember stringing up a raw duck from a beam over the bath to dry out before doing the Peking duck with pancakes! Just buy it ready made from M & S nowadays.
