The measuring jugs I’ve got all have the measurements on the outside, but I rather like the look of this Nigella Lawson measuring jug, which has all the key information on the inside.
From the outside, it looks like an ordinary pink kitchen jug – and there’s no reason why you can’t use it for anything else too – but look inside, and there are all the essential metric and imperial measurements for you to use.
The measuring jug is available from John Lewis and, if pink isn’t your colour, it’s also available in cream.
