Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Beef Hashed
Ingredients
Directions
Prepare the gravy
Break the bones into small pieces.
Stew the bones in water with sweet herbs and a few onions.
In a separate pan, melt butter and mix in flour until browned.

Add the meat, sliced onions, carrot, and parsley to the pan.
Stew gently until the meat is heated through.
Serve hot.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones of the joint
- Simmered in water to produce the flavourful gravy base.
- Butter
- Melts with flour to form a roux that thickens the gravy.
- Flour
- Combines with melted butter to form a roux that thickens the gravy.
- Carrot
- Adds sweetness and aroma to the stewed hash.
The step that matters
Stew gently until the meat is heated through. Gentle heat warms the meat without toughening it, while high heat can make meat dry and tough and can break the gravy.
Swap the onion
How well each one fits the dish's main ingredients (carrot, butter, flour, parsley):
