Hazelnut + Cocoa
Promising but untested: they share 203 flavor molecules (moderate aroma overlap), yet no recipe in our pairing index uses both. They rank in the top 32% of all ingredient pairs.
Do hazelnut and cocoa go together?
Possibly. No recipe in our pairing index uses both, and they share 203 flavor molecules. That places them in the top 32% of every ingredient pair we score.
Why they work
More than half of hazelnut's flavor molecules (203 of 255) also occur in cocoa. Among the shared key aromas are 2-acetyl-1-pyrroline (popcorn, roasted) and 2-acetylpyrazine (roast, tomato).
What each one brings
hazelnut
The tartness. Sour notes make up 17% of its labelled aroma molecules, against 10% for cocoa. It carries 52 molecules cocoa doesn't have.
cocoa
The fruit. Fruity notes make up 21% of its labelled aroma molecules, against 11% for hazelnut. It carries 271 molecules hazelnut doesn't have.
Add a third ingredient
- Vanilla: the best fit for both, top 4% of pairs with hazelnut, top 4% with cocoa.
- Almond: top 1% of pairs with hazelnut, top 15% with cocoa.
- Pistachio: top 1% of pairs with hazelnut, top 21% with cocoa.
- Chocolate: top 7% of pairs with hazelnut, top 9% with cocoa.
Ranked by the average of its two pairing scores. Only foods used in at least 100 recipes are suggested.
Recipes with hazelnut and cocoa
We have no browsable recipe that lists both hazelnut and cocoa. With this much shared aroma, it is the kind of novel pairing worth testing.
Can you swap one for the other?
Only partly. Most of hazelnut's flavor molecules (203 of 255) are also found in cocoa, but cocoa has 271 that hazelnut lacks. Hazelnut gives you part of cocoa's character without most of its fruit. This compares flavor only; texture, moisture and the job each does in a dish matter too.
