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 ↓
Stewed Frogs' Legs
Ingredients
Directions
Prepare
Skin the frogs' legs and soak them in milk for 15 minutes.
Roll the legs in seasoned flour and sauté in hot butter for 3 minutes.
Stew and finish
Cover the legs with hot water and stew until tender, about 20 minutes.
Heat the cream to boiling, then stir in the butter mixed with flour and bring to a boil.
Add the cream mixture to the saucepan with the frogs' legs and season with salt, pepper, and chopped parsley.
Cook gently for 3 minutes and serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Frogs' legs
- Provide the main protein, which becomes tender through stewing.
- Milk
- Softens the legs during the 15-minute soak before cooking.
- Flour
- Coats the legs and thickens the cream sauce when mixed with butter.
- Cream
- Adds richness and body to the finished sauce.
- Butter
- Browns the floured legs and, mixed with flour, helps thicken the sauce.
The step that matters
Stirring the butter-flour mixture into the boiling cream. Flour must be fully dispersed in the hot cream and brought to a boil so it gelatinises and thickens the sauce evenly. Adding it lumpy or undercooked leaves a grainy, thin sauce with a raw floury taste.
Swap the parsley
How well each one fits the dish's main ingredients (milk, flour, pepper, butter, cream):
- Nutmegfits better
- Cinnamonfits better
- Cardamomfits about as well
- Parsleythe original
Fit is the average pairing score against milk, flour, pepper, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
