What they have in common
More than half of onion's flavor molecules (229 of 365) also occur in tea. Among the shared key aromas are 2,4-decadienal (seaweed) and decanal (soap, orange peel). Shared chemistry is a reason to try a pair, not a promise that it works on the plate.

Can you swap one for the other?
