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.
@anon_opin
1) Onions in the fridge?
2) > 2.5kg of Onions in the fridge?!
3) Six onions in a dish?!!
@edinburgh_man @anon_opin 6 onions with that sort of variance is at least a couple dozen onions
@vksxypants @edinburgh_man @anon_opin OP could theoretically have had as few as two onions in the fridge; they are just saying that the smallest was 50g and the largest about 416g. Multiply by 6 to get the numbers in the post. Their point seems to be just that onions vary greatly in size, so “(number of) onions” is not a useful measure.
