Do onion and sriracha go together?
Yes. 246 recipes in our collection combine them, and they share 13 flavor molecules. That places them in the top 22% of every ingredient pair we score.
Why they work
More than half of sriracha's flavor molecules (13 of 23) also occur in onion. Among the shared key aromas are acetic acid (sour, vinegar) and 2-methylbutyraldehyde (malty, chocolate). 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?
