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 ↓
A Hash of Cooked Calfs Head
Ingredients
Directions
Make the gravy
Combine the gravy, catsup, lemon juice, and mushrooms in a stewpan.
Simmer until the mushrooms are tender.
Thicken the mixture with flour, adding more if necessary.
Finish and serve
Add the pieces of calf's head and simmer for 15 minutes.
Garnish with fried or toasted bread and, if desired, egg and forcemeat balls.
If using oysters instead of mushrooms, scald them and add to the gravy, straining the liquor to remove grit.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Cooked meat that forms the body of the hash, heated through in the gravy.
- Flour
- Thickens the gravy so it coats the meat and mushrooms rather than running thin.
- Button mushrooms
- Add earthy flavor and a tender texture to the gravy.
- Gravy or stock
- Provides the savory liquid base that carries the flavor of the whole dish.
The step that matters
Thicken the mixture with flour. Flour must be cooked in the hot liquid to avoid raw, pasty taste and lumps. Adding it gradually, and adding more only as needed, lets you control the thickness before the meat goes in.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, pepper, cream, flour):
- Limefits about as well
- Avocadofits about as well
- Lemonthe original
- Cherryfits about as well
Fit is the average pairing score against mushroom, pepper, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
