Do onion and sturgeon go together?
Yes. 90 recipes in our collection combine them, and they share 41 flavor molecules. That places them in the top 24% of every ingredient pair we score.
Why they work
More than half of sturgeon's flavor molecules (41 of 71) also occur in onion. Among the shared key aromas are 2,4-decadienal (seaweed) and acetoin (butter, cream). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.
