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 ↓
Carrot Soup
Ingredients
Directions
Make the stock
Make a rich stock with the shin of beef, ham, fowl or veal, sweet herbs, onions, a carrot, black and Jamaica pepper, salt, and cloves.
Strain the stock and remove fat when it is cold.
Prepare the vegetables and beef
Clean and boil the red part of the carrots and turnips until very tender.
Pound the carrots and turnips in a mortar.
Warm the cold roast beef or steak and rub it with the carrot mixture through a sieve.
Finish and serve
Add this to the stock and serve boiling hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Pounded and sieved, they thicken the soup and give it body and colour.
- Turnips
- Boiled until very tender and pounded, they add body to the puree.
- Cold roast beef or beef steak
- Warmed and rubbed through a sieve, it adds meaty flavour and body to the soup.
- Shin of beef
- Simmered for a long time, it gives the stock its rich, savoury base.
The step that matters
Rub the carrot mixture through a sieve. Pounding and sieving breaks the cooked vegetables and meat into fine particles, which gives the soup a smooth, even texture. Coarse pieces left behind make the soup grainy.
Swap the turnip
How well each one fits the dish's main ingredients (beef, ham, veal, onion, carrot, butter, pepper):

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