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 ↓
Beef Stock
Ingredients
Directions
Make the stock base
Boil the carrot, turnip, beet, and onions in the beef stock for 45 minutes.
Strain through a sieve and add the can of tomatoes; boil for 15 minutes.
Strain again and season with salt and pepper.
Make the roux and finish the sauce
In a 6‑quart saucepan, heat the butter until light brown.
Add the flour while hot and mix thoroughly.
Remove from heat, add the sugar, and stir until it boils.
Boil for 15 minutes and strain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browned in the pan, it adds fat and a nutty aroma that flavours the sauce.
- Flour
- Mixed with the hot butter to form a roux that thickens the sauce.
- Tomatoes
- Add acidity and body to the stock base.
- Onions
- Simmered in the stock to add savoury sweetness and depth of flavour.
- Beef stock
- Forms the liquid base that carries the flavour of the vegetables.
The step that matters
Adding the flour to the hot butter. Flour added to butter that is too hot or too cool can clump or scorch, leaving lumps or a bitter taste. Mixing thoroughly while the butter is hot helps the flour cook evenly into a smooth roux that thickens the sauce properly.

Fit is the average pairing score against carrot, turnip, onion, beef, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
