Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potato Croquettes Stuffed
Ingredients
Directions
Make the potato dough
In a pot, combine mashed potato, salt, onion juice, pepper, nutmeg, cream, and egg yolks.
Cook over low heat, stirring until smooth.
Shape and fill
Form the potato mixture into balls and scoop out the center to create a cavity.
Fill the cavity with peas, add a little potato back, and reshape the ball.
Coat and fry
Roll each ball in beaten egg, then coat with bread crumbs.
Fry in deep hot oil 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 body of the croquette, giving a soft, starchy interior that holds its shape.
- Egg yolks
- Add richness and help bind the potato mixture as it cooks.
- Cream
- Adds moisture and softness to the potato mixture.
- Peas
- Provide the filling, adding a sweet, tender contrast inside the potato shell.
The step that matters
Cook over low heat, stirring until smooth. Gentle heat lets the egg yolks thicken the mixture without scrambling. High heat can curdle the yolks and leave lumps, making the mixture hard to shape.
Swap the peas
How well each one fits the dish's main ingredients (potato, onion, pepper, nutmeg, cream, egg):
