Onion + Molasses
A cook's pairing more than a chemical one: 524 recipes use both, though they share little aroma. They rank in the top 36% of all ingredient pairs.
Do onion and molasses go together?
Yes, in practice. 524 recipes in our collection combine them, and they share 20 flavor molecules. That places them in the top 36% of every ingredient pair we score.
What they have in common
More than half of molasses's flavor molecules (20 of 26) also occur in onion. Among the shared key aromas are furaneol (caramel, strawberry) and ethanol (alcoholic, ethereal). So the pairing rests more on how cooks use them than on shared aroma.
What each one brings
onion
The sulfurous side. Sulfurous notes make up 13% of its labelled aroma molecules, against 0% for molasses. It carries 345 molecules molasses doesn't have.
molasses
The tartness. Sour notes make up 29% of its labelled aroma molecules, against 15% for onion. It carries 6 molecules onion doesn't have.
Add a third ingredient
- Ginger: the best fit for both, top 9% of pairs with onion, top 14% with molasses.
- Garlic: top 1% of pairs with onion, top 35% with molasses.
- Mustard: top 6% of pairs with onion, top 23% with molasses.
- Clove: top 13% of pairs with onion, top 13% with molasses.

Recipes with onion and molasses
Almost always mains: 66 of the 78 recipes with a course label are mains.
Can you swap one for the other?
Only partly. Most of molasses's flavor molecules (20 of 26) are also found in onion, but onion has 345 that molasses lacks. Molasses 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.
