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 ↓
Mock Fish Balls in Curry or Cream Sauce
Ingredients
Directions
Prepare the balls
Mash the boiled potatoes very fine or strain them through a vegetable strainer.
Mix in the butter, potato flour, beaten eggs, onion juice, salt, and pepper.
Bring a saucepan of salted water to a boil.
Dip a tablespoon in cold water, then scoop the mixture.
Shape into oblong balls.
Carefully drop the balls into the boiling water without crowding.
Cook for 3 minutes.
Remove them as they float to the surface.
Drain the balls in a colander while preparing the sauce.
Make the sauce and serve
Melt the butter in a saucepan.
Stir in the flour and curry powder.
Add milk until the sauce reaches a cream-like consistency.
Add the cooked balls to the sauce.
Bring to a boil.
Remove from heat.
Stir in the Madeira, if using.
Serve on a platter, garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed potatoes form the body of the balls, giving them a soft, tender interior.
- Eggs
- Beaten eggs bind the mixture so the balls hold their shape during cooking.
- Potato flour
- Absorbs moisture and helps the mixture set firmly enough to shape and boil.
- Butter
- Adds richness and fat, keeping the balls tender and the sauce smooth.
- Flour
- Thickens the butter into a roux that gives the curry sauce body.
- Milk
- Forms the liquid base of the cream sauce, carrying the curry flavor.
The step that matters
Cooking the balls in boiling water. Dropping too many balls at once lowers the water temperature and causes them to break apart or cook unevenly. Crowding is avoided by cooking in small batches so the balls set quickly in steady boiling water.
