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
Cut the meat into cutlets and flatten with a rolling pin.
Dip the meat in a mixture of pepper, coarse sea salt, and flour.
Peel and slice the potatoes, using 2 pounds for every pound of meat.
Slice the onions into small bits.
Layer and stew
Melt a little suet or dripping in a pot.
Layer the pot with potatoes, dust with pepper and salt, then add a layer of meat and chopped onions.
Repeat layers until the pot is nearly full.
Add about 1 cup of gravy or water.
Finish with a layer of potatoes on top.
Cover tightly and let stew slowly for about 3 hours, shaking the pot occasionally to prevent burning.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the stew and thicken the liquid as they break down during slow cooking.
- Back ribs or neck of mutton
- Provide the meat and rich flavour that the slow stew draws into the broth.
- Flour
- Coats the meat so the cooking liquid thickens slightly around it.
- Suet or dripping
- Adds fat for browning and a rich, savoury flavour to the pot.
- Onions
- Add sweetness and aroma as they soften and flavour the stew.
The step that matters
Cover tightly and stew slowly. Gentle, covered simmering tenderises tough meat and keeps the potatoes from drying out. Shaking the pot helps stop the bottom from scorching while the liquid is still thin.
