Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Irish Stew
Ingredients
Directions
Brown the mutton
Brown the mutton in its own fat or in a little butter.
Add hot water, pepper, and salt.
Stew
Stir in chopped carrot and turnip, cover, and stew for 1 hour.
Add sliced onions and cook for another hour.
Make and add the crust
In the last 15 minutes, mix flour, baking soda, and cream of tartar.
Rub in butter and add enough water to moisten the mixture.
Roll out the dough thinly to fit the top of the stewpan.
Place the crust over the stew and cook for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fore-quarter mutton
- Provides the meat and fat that flavour the stew and become tender during long simmering.
- Carrot and turnip
- Add sweetness and body to the stew as they soften during cooking.
- Onions
- Break down during stewing, adding sweetness and depth to the broth.
- Flour
- Forms the structure of the dough crust that cooks on top of the stew.
- Baking soda and cream of tartar
- React together to leaven the dough so the crust rises and becomes lighter.
- Butter
- Rubbed into the flour to add richness and tenderness to the crust.
The step that matters
Adding the crust and cooking it on top. The dough must be rolled thin and moistened just enough, since too much water makes it heavy. Cooking it covered on the stew lets the steam set and lighten the crust while it cooks.
Swap the onion
How well each one fits the dish's main ingredients (mutton, butter, pepper, carrot, turnip, flour, cream):
- Leekfits better

- Spinachfits better
- Onionthe original
Fit is the average pairing score against mutton, butter, pepper, carrot, turnip, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
