Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Calf's Head Hash
Ingredients
Directions
Prepare the meat and jelly
Boil the calf's head according to the first direction, then cut all the meat into small square pieces.
Break up the bones and put them with the trimmings into veal stock; stew until reduced and forms a jelly when cool.
Remove the fat from the jelly and place it in a stewpan with Cayenne pepper, salt, mushroom ketchup, and chili vinegar.
Add Madeira or sherry and let it simmer for ten minutes.
Finish and serve
Put in the meat, quenelles of forcemeat, egg yolks, and grated lemon rind; stew for ten minutes.
Serve with the sauce on a hot dish, garnished with pickled gherkins and fried sippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides the meat and gelatin-rich trimmings that give the hash its body.
- Veal stock
- Reduces to a jelly that binds the meat and gives the sauce richness.
- Madeira or sherry
- Adds sweetness and depth to the sauce during simmering.
- Hard-boiled egg yolks
- Enrich the sauce and add a creamy, soft texture.
- Mushroom ketchup
- Adds savoury, umami depth to the sauce.
The step that matters
Reducing the stock to a jelly. Stewing the bones and trimmings until reduced and set when cool is what gives the hash its body. If it is under-reduced, the sauce stays thin; if over-reduced, it becomes too stiff and salty as it concentrates.
