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 ↓
Veal Sweet-breads
Ingredients
Directions
Prepare
Soak the veal sweetbreads in cold water for about 1 hour.
Lard them or draw a pork lardoon through the center of each sweetbread.
Place the sweetbreads in boiling water or stock and boil for 15-20 minutes.
Transfer the sweetbreads to cold water for a few moments until firm and white.
Carefully remove the skinny portions and pipes.
Cook and finish
Place the sweetbreads in a pot and cover with cold water.
Heat the pot to a boil.
Pour off the hot water.
Cover the sweetbreads with cold water until firm.
Add butter before the second boiling.
Stir in a little flour.
Once tender, add a heaping teaspoon of butter, chopped parsley, pepper, salt, and a little cream.
Let the mixture simmer for 5 minutes.
Serve the sweetbreads in a covered dish with gravy poured over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal sweetbreads
- Form the main body of the dish, becoming firm and tender when gently boiled.
- Pork lardoon
- Adds fat that melts during cooking, keeping the lean sweetbread moist and tender.
- Butter
- Enriches the sauce with fat and rich flavor.
- Flour
- Thickens the liquid into a gravy by binding with fat and water.
- Cream
- Adds richness and smoothness to the sauce.
The step that matters
Boiling and cold-water shocking. Boiling firms the sweetbreads and sets their delicate texture, while the cold-water transfer stops cooking so they stay white and firm. Overcooking makes them tough and crumbly.
Swap the parsley
How well each one fits the dish's main ingredients (veal, pork, butter, flour, pepper, cream):
- Nutmegfits about as well
- Sagefits about as well
- Parsleythe original
- Thymefits about as well
Fit is the average pairing score against veal, pork, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
