I've decided Ian or Peter (or whoever it was from the UK who pointed this out a while ago) is right, and we would all be better off if recipes worked purely on weight measurements rather than anything else. Sometimes a half cup of brown sugar, firmly packed, can weigh 25% more or less than other times, depending on
how firmly it's packed. And darn it all, exactly how much onion is there in "2 onions, finely chopped" ? I've seen an onion which is three times bigger than the one right next to it. I'd make an exception for quantities less than say a couple of teaspoons, but even when you get to tablespoon measures, it becomes confusing, as a US Tbsp is 15ml, whereas an Aus one is 20ml (as far as I can tell, a standard tsp is 5ml everywhere).
Can someone please tell me why US cookbooks often refer to butter in tablespoons? I've seen cake recipes that specify "16 Tbsp unsalted butter", and I've never understood why - does butter in the US come in a tub that can be scooped out with a Tbsp? Over here it usually comes in a 250g block.
Aaaah. I feel better now I've got that off my chest, thanks for listening.
Cheers, and Happy New Year to you all!
