Why they work

Almost everything snapper carries, onion has too: 25 of snapper's 27 flavor molecules also occur in onion. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.

Can you swap one for the other?

Only partly. Almost all of snapper's flavor molecules (25 of 27) are also found in onion, but onion has 340 that snapper lacks. Snapper gives you part of onion's character without most of its sulfurous side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
