Thanks all. If anyone asks what I want/need as a housewarming gift I'm going to suggest they get me some cook books so I'll take a look at the ones suggested then send out my amazon wish list :)
if you are just learning to cook Evian, try Delia's cookery course, or the How to Cook books she did, and try Mary Berry, her everyday recipes are really nice - I prefer her recipe for meatloaf to my mum's one.
I think it is important to differentiate between baking soda and baking powder. Baking soda is bicarb with some kind of filler (cornflour has been suggested) baking powder is bicarb with cream of tartar. the alkali and acid mix together to make the bubbles....However, recipes which specify plain flour plus baking powder may well use a higher ratio of raising agent than that usually contained in SR flour. For instance scones can have four times as much baking powder. Most tubs of baking powder have the proportions of flour/powder. Good luck with your baking. Stick with it. It will bring much pleasure to you and your "victims" eventually.....LOL
