Oh heck. I lived in the UK for years but never got around to buying a scale (had baked for years with Canadian cups).
My son got me a scale and now I’m trying to make bagels from an Irish recipe (bit odd, but there you are) & am having massive brain fluff re liquid. If it says 300 grams of water does it mean weight or volume?
Might be blindingly obvious to you lot but not to colonials!
