Why it works: Liver and horseradish work together. They rank in the top 13% of all ingredient pairs, and 42 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the head
Soak the calf's head in cold water for 2 hours.
Remove the brains and scrape the head clean.
Flour a cloth, wrap the head tightly, and place it in 6 to 8 quarts of water with the salt pork.
Tie the brains in a separate piece of cloth.
Boil
Boil the head for 2 hours.
Add the liver, lights, and brains to the pot.
Boil for 2 more hours.
Remove the cloth; the bones will come out easily.
Place the head skin side up on a dish to keep warm while making the gravy.
Make the gravy and serve
In a saucepan, combine the boiling liquid, chopped liver, braided brains, butter, flour, pepper, salt, and sweet marjoram.
Bring the mixture to a boil.
Add vinegar.
Divide the liver and head, skin the tongue, and arrange it around the head on the dish.
Pour some gravy over the head.
Serve the rest of the gravy in a gravy dish.
Garnish with scraped horseradish and lemon slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Forms the main body of the dish, cooked slowly until tender enough for the bones to lift out.
- Salt pork
- Adds savory fat and seasoning to the cooking liquid, enriching the broth.
- Butter
- Adds fat and richness to the gravy, giving it a smooth mouthfeel.
- Flour
- Thickens the gravy by binding with the butter and cooking liquid.
- Vinegar
- Adds acidity that brightens the rich gravy and balances its fattiness.
- Liver
- Contributes deep, rich flavor and body to the gravy.
The step that matters
Adding the flour and butter to the gravy. Flour must be cooked into the butter and hot liquid while stirred, or it forms lumps instead of a smooth thickened gravy. Adding vinegar only after the mixture boils keeps its sharp flavor bright.
