@blogdiva we (@steggy and I) lived in London for 10 years. We learned to cook in metric because you must. But now we are back in America and we cook metric still. Once you learn it, it’s ridiculous to have umpteen spoons and cups and things to measure by volume when you can just use mass.
When you cook metric you throw a bowl on top of your scale, tare to zero and start adding. 200ml of water? Add water until it says 200g. 800g of flour? Into the bowl on the scale. 10g of salt? Into the bowl. No spoons. No cups. Less dish washing. Faster and easier.
But yes, in the UK generally the only food measurements are metric. There’s a “pint” for beer (shhh. Don’t tell them it is 500ml). There’s miles and miles-per-hour for driving. Virtually everything else is metric.
A bunch of my American cookbooks have metric measures pencilled in.
Why she is doing cooking in colonial units (😜) is a mystery unless it’s deliberately made for the US audience.
