Why it works: Pepper and parsley 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 ↓
Cream of Lettuce Soup
Ingredients
Directions
Prepare the lettuce
Wash and drain the lettuce, then chop it.
In a large pot, melt the butter and cook the chopped lettuce for 4–5 minutes, stirring lightly.
Make the soup
Add the water, season with salt, pepper, and parsley, and stir in the rice.
Cover the pot and cook for 40 minutes, then strain the mixture.
Clean the pot, return the soup to it, and bring to a boil.
Stir in the sweet cream and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the body of the soup and gives it its fresh, green flavour.
- Butter
- Adds fat and richness, and helps soften the lettuce as it cooks gently.
- Uncooked rice
- Thickens the soup as its starch softens during the long simmer.
- Sweet cream
- Adds richness and a smooth, velvety texture when stirred in at the end.
The step that matters
Stirring in the sweet cream. Cream can curdle or separate if it boils hard, so it is added after the soup has been brought to a boil and then served promptly.
Swap the lettuce
How well each one fits the dish's main ingredients (butter, pepper, parsley, rice, cream):

Fit is the average pairing score against butter, pepper, parsley, rice, cream. Candidates are from the same food group and used in at least 100 recipes.
