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 ↓

Butter and flour 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
- Veal brains
- Provide the tender, delicate body of the filling.
- Sweetbreads
- Provide a soft, creamy texture that makes up the bulk of the filling.
- Cream
- Adds richness and body, helping the sauce coat the filling smoothly.
- Flour
- Thickens the sauce so it holds together around the filling.
- Butter
- Adds fat and richness to the sauce and carries flavor.
- Sherry
- Adds acidity and aromatic depth to the finished sauce.
The step that matters
Adding the cooked brains and sweetbreads to the sauce. Sauce thickened with flour can become lumpy or thin if the flour is not cooked out and the liquid is not kept at a steady simmer. Adding sherry and the cooked meats to a sauce that is still too thin or too hot can break it or dilute its body.
Swap the parsley
How well each one fits the dish's main ingredients (veal, butter, sherry, flour, cream, pepper, chicken):
- Nutmegfits about as well
- Thymefits about as well
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against veal, butter, sherry, flour, cream, pepper, chicken. Candidates are from the same food group and used in at least 100 recipes.
