I heard a piece of advise or rather knowledge the other week that I never thought of before but makes complete sense. Did you know that the number of leaves an onion has is the same number of layers the onion will have? Of course that makes perfect sense! So I know this onion will have 10 layers (always an even number as their leaves grow in pairs) when I cut into it. Same goes for garlic, the number of leaves equals the number of cloves. Duh!
