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 ↓
Irish Stew
Ingredients
Directions
Prepare the meat
Flatten the meat cutlets with a rolling pin.
Dip the flattened cutlets in a mixture of pepper, salt, and flour.
Layer and stew
Layer half of the sliced potatoes in a pot and dust with pepper and salt.
Add a layer of meat sprinkled with chopped onions.
Repeat the layers until the pot is nearly full.
Pour in the gravy or water.
Finish with a final layer of potatoes on top.
Cover the pot tightly.
Let it stew slowly for about 3 hours, shaking occasionally to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Bulk the stew and thicken the liquid as their starch softens during slow cooking.
- Meat (back ribs or neck of mutton)
- Supplies rich flavor, and collagen that softens into tender meat over long, slow cooking.
- Onions
- Add sweetness and savory depth as they cook down into the broth.
- Flour
- Coats the meat and helps thicken the stew's liquid into a light gravy.
The step that matters
Shaking to prevent burning. The stew sits for hours with little liquid at the bottom of the pot, so it can scorch. Shaking the covered pot occasionally redistributes liquid and keeps the base from sticking and burning.
Swap the onion

Fit is the average pairing score against potato, mutton, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
