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 ↓
Irish Stew
Ingredients
Directions
Make the stew
Cover the meat with cold water in a pot and bring to a boil.
Reduce heat to a gentle simmer and cook for 1 hour until the meat is tender.
Add the sliced onion, pepper, salt, and mace, tasting the broth as you season.
Cover and stew for another hour.
Finish and serve
Boil the potatoes separately until tender, then cut them into small pieces.
Add the potatoes to the stew and stir to combine.
Mix the flour with a little cream to make a smooth thickening, then stir it into the stew.
Add the remaining cream, bring to a boil, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or mutton
- Provides the main protein, which becomes tender through long, gentle simmering.
- Potatoes
- Break down slightly as they cook, adding body and starch to the stew.
- Flour
- Thickens the stew's liquid as it heats, giving it a smoother body.
- Cream
- Adds richness and a silky mouthfeel to the finished stew.
- Onion
- Releases sweetness and savory depth into the broth as it cooks.
The step that matters
Thickening with flour and cream. Flour mixed into cold cream first disperses evenly, so it thickens smoothly instead of forming lumps when stirred into the hot stew.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (beef, onion, pepper, potato, flour, cream):
- Garlicfits better
- Celeryfits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against beef, onion, pepper, potato, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
