Onion in recipes should be by weight not number, as they vary by size considerably. Tonight's dish requires "6 onions" which is anything from 300g to nearly 2.5kg. Based on what we had in our fridge, that is.

It is 2 kilos. 2 kilos of onions for 4 portions. Don't worry, they lose a lot of water when you caramelise them properly.

Also, 10 cloves of garlic, not one.
