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 ↓
Potato Croquettes
Ingredients
Directions
Make the mixture
In a bowl, mix the hot mashed potatoes, butter, white pepper, cayenne, salt, and celery salt until very light.
Once slightly cool, add the egg yolk and mix well.
Rub the mixture through a sieve and fold in the chopped parsley.
Shape and coat
Shape the mixture into rolls, then roll in bread crumbs.
Dip the rolls in the beaten egg, then roll in crumbs again.
Fry and serve
Fry in smoking hot lard for one minute until golden.
Serve on a bed of French peas heated with butter and cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provide the bulk and soft body that holds the croquette shape.
- Egg yolk
- Adds richness and helps bind the mixture so it holds together when shaped.
- Butter
- Adds fat and richness, softening the potato mixture for a light texture.
- Bread crumbs
- Form a crisp, golden browned crust when fried.
- Egg
- Coats the rolls so the bread crumbs adhere and form an even crust.
The step that matters
Fry in smoking hot lard. The fat must be very hot so the crumb coating browns quickly and seals before the potato interior absorbs grease and softens. Frying in cooler fat produces greasy, pale croquettes that may fall apart.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, butter, pepper, celery, egg, parsley, bread):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against potato, butter, pepper, celery, egg, parsley, bread. Candidates are from the same food group and used in at least 100 recipes.
