Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Sweet and White Potato Croquettes
Ingredients
Directions
Prepare
Combine mashed potato, butter, pepper, salt, celery salt, onion juice, parsley, and egg yolk in a bowl.
If the mixture is not moist enough to mold, add a little cream or milk.
Shape and fry
Shape the mixture into croquettes, then roll them in bread crumbs.
Heat oil in a pan until smoking hot, then fry the croquettes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potato
- Forms the bulk of the croquettes and gives them a soft, moist interior.
- Butter
- Adds richness and fat, keeping the inside tender.
- Egg yolk
- Binds the mixture so the croquettes hold their shape.
- Bread crumbs
- Form a crisp, golden crust when fried.
The step that matters
Frying the croquettes. If the oil is not hot enough, the croquettes absorb oil and turn greasy before the crust sets. Smoking-hot oil seals the bread crumbs quickly, producing a crisp exterior while the potato inside heats through.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, pepper, celery, parsley, egg, cream):

- Onionthe original
Fit is the average pairing score against potato, butter, pepper, celery, parsley, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
