I'm all for respecting cultural differences, but...

I love the internet as a source of recipes, but when they give ingredients US-style it drives me nuts. I think the one currently in the oven will be fine with approximate amounts which is good because it called for a pint of cherry tomatoes and a quarter of a cup chopped onion.
Not wanting to disrespect lovely US Mumsnetters, but seriously, kitchen scales are an amazing invention!

I have a recipe for sugar cookies, in cups. I love it, it makes so many! Lots more than pounds and ounces…

Onions vary greatly in size.
A quarter cup is more precise.
Having said that, my heart sinks when I see an American recipe because it takes time to convert.
Their cups are slightly different from English ones!

I didn't know English cup sizes were even a thing! Anyway, if you don't have American cup measures you just need to remember that 1 cup = 8 fl oz. (Also there are 16 tablespoons in a cup, so, for example, 1/4 cup = 4 tablespoons.)
