Why it works: Onion and potato 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 ↓
Chicken Hash
Ingredients
Directions
Prepare the chicken
Boil the chicken thoroughly and remove it when done.
Return the pot to the fire and make a strong broth.
Strip the meat from the chicken in large pieces and cut into small squares.
Make the hash
In a pan, melt the butter and add the finely chopped onion; cook thoroughly.
Add the chicken and boiled potatoes to the pan.
Stir in the chopped hard boiled eggs, salt, pepper, and pimento pepper.
Pour in an equal quantity of the prepared broth and cream.
Cook slowly, stirring constantly until the mixture reaches the proper consistency for serving as hash.
Just before serving, stir in the yolks of the raw eggs for a rich color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main body of the hash as tender meat and flavorful cooking liquid.
- Butter
- Adds fat for richness and carries the onion flavor into the pan.
- Potatoes
- Add starchy body that thickens the hash and gives it a soft, hearty texture.
- Cream
- Adds fat and richness, giving the hash a smoother, creamier texture.
- Raw egg yolks
- Add richness and color, and thicken the mixture when gently heated.
The step that matters
Adding the raw egg yolks. Egg yolks thicken when heated but can scramble if the mixture is too hot or boils after they go in. Stirring them in just before serving, off strong heat, keeps the hash smooth and creamy.
