An ingress chat pointed out Aussie tablespoon is 20ml rather than 15ml being used in like UK and US. I was shoot I had no idea. Then had a horrifying finding that I have one being 15ml and the other being 20ml. I’ve been using them together for years without realising one is 33% bigger than the other.
@eth Cooking measurements are wild! Why I keep my baking to either american recipes (as I'm in america with those measurements) or ones that use weight measurements and pop out a scale!
