Why it works: Beef and pork match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,690 recipes. Both carry 12-methyltridecanal, which smells tallowy, beefy. The science ↓
Irish Stew
Ingredients
Directions
In a large pot, combine the mutton, beef, veal, and pork chops.
Add the quartered potatoes and sliced onions.
Season with salt and pepper, then pour in the gravy and catsup if using.
Cover the pot tightly and simmer on low heat for 2 hours, stirring occasionally to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton chops
- Provide the rich meat base and savory flavor that defines the stew.
- Irish potatoes
- Thicken the broth as they break down and add starchy body to the stew.
- Onions
- Add sweetness and aroma as they soften and melt into the broth.
- Gravy
- Adds moisture and savory depth to the liquid surrounding the meat.
The step that matters
Simmering the covered pot. Low, gentle heat lets the tough meat become tender without drying out, while stirring prevents the starches and sugars on the bottom from scorching.
