Cream + Onion
A good pairing. Cooks put them together in 10,827 recipes, and they share 44 flavor molecules: the top 18% of all ingredient pairs.
Do cream and onion go together?
Yes. 10,827 recipes in our collection combine them, and they share 44 flavor molecules. That places them in the top 18% of every ingredient pair we score.
Why they work
More than half of cream's flavor molecules (44 of 71) also occur in onion. Among the shared key aromas are 2-nonanone (fruity, floral) and acetic acid (sour, vinegar). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.

Recipes with cream and onion
Almost always mains: 932 of the 1,106 recipes with a course label are mains (from a sample of 3,000 recipes that use both).
Can you swap one for the other?
Not really. Each has a lot the other lacks: cream has 27 molecules onion doesn't, and onion has 321 that cream doesn't. Treat them as partners, not stand-ins. This compares flavor only; texture, moisture and the job each does in a dish matter too.
