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 ↓
To Make a Hash
Ingredients
Directions
Prepare the broth
Cut the cold meat from the bone into nice slices and set aside.
In a stewpan, melt the butter over low heat and add the sliced onion, carrot, and turnip.
Brown the vegetables gently, then add the bones, water, pepper, and salt.
Boil until the liquid reduces by one-third, then strain the broth.
Make the gravy
Make a brown roux and gradually add the hot gravy, boiling to remove the raw flour taste.
If the gravy is not rich enough, stir in the brown sugar and adjust the color with browning sauce if needed.
Heat and serve
Place the slices of cold meat in the stewpan by the side of the fire to heat thoroughly without boiling.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the main body of the dish, heated through gently in the finished gravy.
- Onion
- Browned gently with the other vegetables to add savory sweetness and aroma to the broth.
- Carrot
- Browned gently with the onion to add natural sweetness and depth to the broth.
- Turnip
- Browned with the other vegetables to add body and mild earthy flavor to the broth.
- Butter
- Fat that softens and browns the vegetables and forms the base of the roux.
The step that matters
Boiling the gravy after adding the hot broth to the roux. Flour thickens only when its starch cooks fully; boiling the gravy removes the raw flour taste and lets it thicken smoothly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (meat, carrot, turnip, butter, pepper, sugar, sauce):
- Parsnipfits better

- Onionthe original
Fit is the average pairing score against meat, carrot, turnip, butter, pepper, sugar, sauce. Candidates are from the same food group and used in at least 100 recipes.
