Conversion tables
All these are approximate conversions, which have either been rounded up or down. In a few recipes, it has been necessary to modify them very slightly. Never mix metric and imperial measures in one recipe; stick to one system or the other.
All spoon measurements on this site are level, unless specified otherwise.
All butter is salted, unless specified otherwise.
In Delia's recipes she uses large eggs, unless otherwise stated.
All recipes are tested using whole milk, unless specified otherwise.
