Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
To Broil Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Split the sweetbreads in half with a sharp knife.
Lay the sweetbreads on a grill and broil both sides for about 3 minutes.
In a saucepan, combine hot water, butter, flour, pepper, salt, and cream. Stir the mixture and bring it to a boil.
Pour the hot sauce over the sweetbreads.
Cook the calf's head
Soak the calf's head in cold water for 2 hours.
Remove the brains from the calf's head and clean the head thoroughly.
Flour a cloth. Tightly wrap the calf's head in the cloth.
Boil the wrapped head in 6 to 8 quarts of water with salt pork for 2 hours.
Tie the brains in a separate cloth. Add the wrapped brains, liver, and lights to the pot.
Boil for an additional 2 hours.
Remove the cloth from the head. Extract the large bones from the head.
Place the head skin side up on a dish to keep warm.
Make the gravy and serve
In a saucepan, combine 1 quart of the boiling liquid, finely chopped liver, prepared brains, butter, flour, pepper, salt, and sweet marjoram. Bring the mixture to a boil.
Add vinegar to the sauce.
Serve the liver and head on a dish. Garnish with scraped horseradish and lemon slices.
Pour some gravy over the head and serve the rest separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main meat; split and broiled so the surface browns while the inside stays tender.
- Flour
- Thickens the butter and cream sauce so it coats the meat and gravy.
- Butter
- Adds richness and fat to the sauce, helping it feel smooth on the palate.
- Cream
- Adds moisture and richness, giving the sauce a softer, smoother body.
- Vinegar
- Adds acidity that sharpens and balances the rich, fatty gravy.
- Liver
- Adds deep, savory flavor to the gravy when finely chopped and simmered.
The step that matters
Bringing the gravy to a boil with flour and butter. Flour must be cooked in the hot liquid long enough to thicken smoothly. Whisking or stirring while it boils prevents lumps and a raw floury taste.
Swap the horseradish
