Weights and Measures

Weights and MeasuresIt may sound obvious but getting the correct ingredients and their quantities right are important to successful and consistent cooking. I’ve found this easier said than done, though, particularly when I’ve collected recipes from friends and relatives, and books and magazines, from North America and the U.K. and it’s not always clear where they’re from.

So is that recipe referring to a U.S. or an imperial pint? Is that liquid being measured in ounces or fluid ounces?

I should say that I’m strongly in favour of using scales for dry ingredients and measuring jugs or cups for liquids. I know that cups are very popular, particularly in the U.S., for measuring dry ingredients but the amounts can vary quite a lot depending on how you scoop and how densely the ingredient was packed.

The safest way is to use grams (g) or ounces (oz) for dry ingredients and millilitres (ml) or fluid ounces (fl oz) for liquids. No converting necessary!

I’ve tried to include all options in my individual recipes but felt that it would be helpful to pull it together into one section.

Hope this helps!
