Why it works: Parsley and carrot 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 ↓
Turtle Soup
Ingredients
Directions
Prepare the turtle
Kill the turtle the evening before use, dress it, and soak in salt water overnight.
Boil the turtle in enough water to make soup, allowing for evaporation.
Add salt and cook until tender, along with the bacon or ham.
Remove all the meat and set aside to cool.
Make the soup
Chop the assorted vegetables, parsley, carrot tops, onion tops, and celery tops finely.
Mince the meat and combine it with the chopped vegetables.
Boil the mixture for 10 minutes.
Make a thickening by mixing the sweet cream and flour, then pour it into the boiling soup.
Cook for an additional minute and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turtle
- Forms the main body of the soup and supplies the meat for the bowl.
- Bacon or ham
- Adds savory, smoky fat and salty flavor to the broth.
- Sweet cream
- Adds richness and body to the soup once combined with the thickening.
- Flour
- Thickens the soup when mixed with cream and stirred into the boiling liquid.
The step that matters
Adding the cream and flour thickening. Flour mixed directly into hot liquid clumps. Blending it smoothly with the cream first lets the starch disperse evenly, so it thickens the soup without lumps.
Swap the onion
How well each one fits the dish's main ingredients (ham, parsley, carrot, celery, cream, flour):
- Parsnipfits better
- Turnipfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against ham, parsley, carrot, celery, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
