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 ↓
Chicken Hash
Ingredients
Directions
Prepare
In a saucepan, bring some water to a boil.
Add the potatoes and cook until tender.
Make the hash
Stir in the chopped chicken and season with black pepper, coarse sea salt, and red pepper.
In a small bowl, mix the butter and flour together.
When the hash is nearly done, add the butter‑flour mixture and cook for a few more minutes.
If desired, add chopped onion or substitute old biscuit for the potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starchy bulk and body that gives the hash its substance and texture.
- Butter
- Adds richness and fat, carrying flavour and helping the mixture brown.
- Flour
- Mixed with butter and cooked in, it thickens the hash and binds it together.
- Cooked chicken
- Supplies the main protein and savoury flavour of the hash.
The step that matters
Adding the butter-flour mixture. Flour added to a hot mixture can clump if not blended with fat first; cooking it a few minutes removes raw flour taste and lets it thicken evenly.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (chicken, butter, flour, pepper, onion, biscuit):
- Chivefits about as well
- Potatothe original
- Okrafits about as well
- Spinachfits about as well
Fit is the average pairing score against chicken, butter, flour, pepper, onion, biscuit. Candidates are from the same food group and used in at least 100 recipes.
