Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the head and stock
Wash the calf's head in water to remove blood and impurities.
Cut the flesh from the bones and tie it in a clean cloth.
Place it in a large stew-pan with the bones and 4 quarts of cold water and ½ tablespoon of salt.
Bring to a boil, skim well, then reduce heat and simmer for 3 hours, skimming occasionally.
Remove the calf's head, strain the stock, and set aside to cool.
Once cool, remove all fat from the stock.
Make the soup
Melt 1 ounce of butter in a stew-pan over heat.
Slice the ham and clean and slice the vegetables.
Fry the ham and vegetables in the butter for 10 minutes, adding spices and herbs.
Stir in 3 ounces of flour, then add the stock and stir until boiling.
Reduce heat and let simmer for about 10 minutes, removing any scum.
Strain the soup into another saucepan.
Finish and serve
Cut the meat from the calf's head into small pieces and add to the soup along with ⅔ cup sherry and the force-meat balls.
Squeeze in the juice of ½ lemon through a strainer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the gelatinous meat and body that give the soup its rich texture.
- Butter
- Fat for frying the ham and vegetables, carrying their aroma into the soup.
- Flour
- Thickens the stock into a smooth, lightly bodied soup as it boils.
- Sherry
- Adds sweetness and acidity that rounds out the rich stock.
- Lean ham
- Contributes savoury, salty depth to the frying base and the finished soup.
- Lemon juice
- Adds acidity that brightens the heavy, rich stock.
The step that matters
Stirring in the flour. Flour must be cooked into the butter and then stirred into boiling stock; adding it without enough stirring can leave lumps and a raw, pasty taste, while cooking it briefly lets the starch thicken the soup smoothly.
