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 ↓
Vegetable Cutlets
Ingredients
Directions
Prepare the vegetables
Steam or boil the diced turnip and potato until tender, then drain.
Wash the peas and let them stand in cold water for 30 minutes, then drain well.
Make the sauce
In a saucepan, melt the butter, add the flour, and stir to make a thick white sauce.
Gradually add the milk, stirring until the sauce is smooth and thickened.
Season the sauce with salt, white pepper, and onion juice.
Carefully mix in the turnips, potatoes, and half of the peas.
Shape and fry
Butter a shallow pan and spread half of the reserved peas on the bottom.
Pour the vegetable mixture over the peas and top with the remaining peas, pressing them in lightly.
Set aside until cold and firm.
Turn out onto a board, cut into wedges, dip each in beaten egg, and roll in dry crumbs.
Fry in hot oil until golden brown and decorate each cutlet with a green frill.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White turnip
- Provides bulk and a mild body that holds the cutlet mixture together.
- Irish potato
- Starch thickens the mixture and gives a soft, cohesive texture once cooled.
- Flour
- Thickens the butter and milk into a white sauce that binds the vegetables.
- Milk
- Forms the liquid base of the sauce, giving it smoothness and richness.
- Egg
- Beaten egg coats the cutlets and sets to help the crumbs adhere when frying.
The step that matters
Set aside until cold and firm. The sauce and starches must cool and set fully; cutting or dipping a warm mixture makes it crumble or fall apart in the hot oil.
Swap the white pepper
How well each one fits the dish's main ingredients (turnip, potato, peas, butter, flour, milk, onion):
- Capersfits better
- Thymefits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against turnip, potato, peas, butter, flour, milk, onion. Candidates are from the same food group and used in at least 100 recipes.
