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.

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
- The main ingredient, which becomes tender through slow stewing in liquid.
- Flour
- Coats the legs and thickens the sauce when cooked with butter and liquid.
- Butter
- Adds fat and richness, and browns the legs when sautéed in it.
- Cream
- Adds richness and a smooth, creamy body to the finished sauce.
The step that matters
Stir in the butter rolled in flour and boil briefly. The flour and butter mixture thickens the sauce as its starch swells in boiling liquid. Adding it to liquid that is not hot enough, or stirring too little, can leave lumps and a thin, floury sauce.
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.
