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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that forms the body of the fricassee.
- Butter
- Adds richness and carries flavour, and with the flour forms the base of the sauce.
- Flour
- Thickens the butter and stock into a smooth sauce.
- Egg
- Enriches and thickens the sauce when stirred in off the heat without curdling.
- Cream
- Adds richness and a smooth, silky texture to the finished sauce.
- White stock
- Supplies the liquid base that the flour thickens into the sauce.
The step that matters
Stir the egg and cream into the sweetbreads off the heat. Egg proteins set at moderate heat and can scramble or curdle if the mixture is too hot. Removing the pan from the heat before stirring in the egg-cream mixture lets it thicken the sauce gently and keeps it smooth.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, egg, cream, nutmeg, pepper):
- Cinnamonfits about as well
- Parsleythe original
- Tarragonfits about as well
- Cardamomfits less well
Fit is the average pairing score against butter, flour, egg, cream, nutmeg, pepper. Candidates are from the same food group and used in at least 100 recipes.
