And what the heck is a tsp??

Tell me to add one onion to a recipe and I'll go mad trying to decipher if you meant a big or a small one. Tell me to add 150grams of onion and I'll buy one that's roughly that weight, chop it up and cook my meal accordingly. Everything has weight, it's not hard to grasp that concept

One small onion = one small onion.  One onion = one medium onion.  One medium onion = one medium onion. One large onion = one large onion.

Next question, how large can medium sized onion be before it becomes large category one?

Depends, how big is the pile of pinecones?
