Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Croquettes
Ingredients
Directions
Prepare
Peel and mash the potatoes.
Season with salt, butter, and white pepper.
While hot, beat in the egg yolks.
Shape and coat
Form the mixture into balls the size of a small apple.
Roll each ball in flour, then in beaten eggs, and finally in bread crumbs.
Make an impression in each ball with your thumb to resemble an apple.
Brown and serve
Brown the croquettes in hot oil.
Serve on a fancy folded napkin with a sprig of parsley in the impression.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the croquettes and give a soft, absorbent interior.
- Egg yolks
- Bind the mashed potato mixture and add richness to its texture.
- Butter
- Adds fat and flavor, keeping the potato interior soft and rich.
- All-purpose flour
- Creates a dry first coating that helps the beaten egg adhere.
- Eggs
- Form a binding coating that helps bread crumbs stick to the outside.
- Bread crumbs
- Provide a crisp outer layer that browns when fried.
The step that matters
Brown the croquettes in hot oil. The coating must be fully set and the oil hot enough to crisp the crumbs quickly. Oil that is too cool lets the croquettes absorb grease and turn soggy, while the potato interior needs the coating to hold it together.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, butter, egg, flour, bread, parsley):
- Capersfits better
- Nutmegfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against potato, butter, egg, flour, bread, parsley. Candidates are from the same food group and used in at least 100 recipes.
