Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Turtle Soup
Ingredients
Directions
Prepare the turtle
Boil the turtle until tender, then separate the meat from the bones and chop it finely.
Strain the broth in which the turtle was cooked.
Make the soup
Add the diced potatoes, can of tomatoes, corn, and rice to the broth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turtle
- Provides the main meat and flavour of the soup.
- Potatoes
- Soften during simmering and thicken the broth slightly as their starch releases.
- Flour
- Creamed with butter, it thickens the broth into a smoother body.
- Butter
- Adds richness and carries flavour, and when creamed with flour it helps thicken the soup.
- Rice
- Absorbs liquid and adds body as it cooks into the broth.
- Tomatoes
- Add acidity and savoury depth to the broth.
The step that matters
Adding the butter and flour mixture. Flour added directly to hot liquid clumps. Creaming it with butter first and adding it slowly while stirring lets the starch disperse evenly and thicken the broth smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (potato, corn, rice, parsley, pepper, butter, flour):
- Carrotfits better
- Okrafits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against potato, corn, rice, parsley, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
