Spread + Onion
A good pairing. Cooks put them together in 148 recipes, and they share 39 flavor molecules: the top 25% of all ingredient pairs.
Do spread and onion go together?
Yes. 148 recipes in our collection combine them, and they share 39 flavor molecules. That places them in the top 25% of every ingredient pair we score.
Why they work
More than half of spread's flavor molecules (39 of 54) also occur in onion. Among the shared key aromas are ethyl acetate (pineapple, fruity) and ethanol (alcoholic, ethereal). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.
What each one brings
spread
The tartness. Sour notes make up 30% of its labelled aroma molecules, against 15% for onion. It carries 15 molecules onion doesn't have.
onion
The sulfurous side. Sulfurous notes make up 13% of its labelled aroma molecules, against 2% for spread. It carries 326 molecules spread doesn't have.
Add a third ingredient

Can you swap one for the other?
Only partly. Most of spread's flavor molecules (39 of 54) are also found in onion, but onion has 326 that spread lacks. Spread 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.
