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 ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the stock
Soak the calf's head in cold water and wash it thoroughly.
In a large pot, boil the head in 6 quarts of water for 4 hours.
Strain the broth into a jar and let it cool overnight; skim off the fat.
Make the soup
In a pot, combine 2 quarts of the broth, cloves, peppercorns, salt, onions, carrots, and turnips; boil for 2 hours.
Cut the remaining meat from the head into small pieces and add to the pot; boil for 1 hour.
Strain the vegetable broth into the pot and boil for another 1.5 hours.
Mix 3 tablespoons of browned flour with ½ pound of butter; stir into the soup and boil for 10 minutes.
Add ½ pint of red wine and give it one final boil.
Serve
In a tureen, place the forcemeat balls, lemon slices, yolks of hard-boiled eggs, and soy sauce.
Pour the hot soup over the ingredients in the tureen and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Browned flour
- Thickens the broth, giving the soup a fuller body.
- Butter
- Adds richness and fat, rounding out the flavour and body of the soup.
- Red wine
- Adds acidity and depth of flavour to the finished soup.
- Hard-boiled eggs
- Yolks add richness and a creamy texture to the soup.
- Calf's head
- Supplies gelatin and meat flavour, giving the stock body and savour.
The step that matters
Skimming the cooled broth. Fat solidifies on top of the chilled broth and is easy to remove as a layer. Leaving it in would make the finished soup greasy and heavy.
