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 ↓
French Fried Potatoes
Ingredients
Directions
Prepare the potatoes
Cut potatoes into slices one inch or more in width and thickness.
Take potatoes freshly boiled in salted water.
Drain the potatoes.
Cut the boiled potatoes into thin slices.
Fry the slices
Drop the slices into boiling fat. Fry for 5 minutes.
Take out with a skimmer. Drain the fried potatoes.
Lightly dredge with salt. Serve on a hot dish.
Fry in butter with gravy
Put the sliced potatoes in a hot frying pan with melted butter. Cook for about 10 minutes, stirring occasionally.
Boil potatoes in their skins.
When cold, peel and cut the potatoes into small pieces.
Put the pieces in a skillet with butter or half lard and butter. Fry until brown.
Make a good cream gravy as for chicken. Pour the gravy over the potatoes.
Let the potatoes cook up well. Serve immediately.
Raw potato slices and potato cakes
Peel and slice raw potatoes thin. Throw the slices into cold water. Drain the slices.
Put the slices into a frying pan with 1 tablespoon hot dripping. Fry until brown.
Grate 6 large raw potatoes. Add 2 well beaten eggs. Add 2 tablespoons flour.
Add 1 teaspoon soda in a cup of sour milk. Add a pinch of salt. Fry like pancakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish and brown on the outside when fried.
- Eggs
- Bind the grated potato together so the cakes hold their shape.
- Flour
- Adds starch that helps the batter bind and set during cooking.
- Soda with sour milk (in the method)
- Reacts with the sour milk's acid to lighten the batter as it cooks.
- Dripping (in the method)
- Hot fat conducts heat evenly and gives the potatoes a crisp, browned surface.
- Butter (in the method)
- Adds fat for browning and a rich, buttery flavor.
The step that matters
Frying in hot fat. The fat must be hot before the potato slices go in. If it is not hot enough, the slices soak up grease, turn soggy and fail to brown and crisp on the outside.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, flour, pepper):
- Chivefits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against potato, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
