Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Calf's Head Hash
Ingredients
Directions
Prepare the head
Wash the calf's head and boil until tender.
Remove the bones from half of the head and set aside.
Beat the egg and brush it over the head.
Sprinkle the head with grated bread, lemon peel, thyme, and parsley.
Add breadcrumbs and place in a Dutch oven to brown.
Make the hash
Cut the other half of the head into dice and place in a saucepan.
Add gravy, forcemeat balls, white wine, and ketchup; warm together.
Skim off any fat and peel the tongue.
Make the brain cakes and serve
Mix brains with flour, eggs, lemon peel, thyme, parsley, and seasonings.
Form into small cakes and fry until light brown.
Serve the tongue with the brains arranged around it.
Dish the hash with the browned head in the center and garnish with bacon and bread snippets.

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 meat of the hash, providing body and rich flavor.
- Egg
- Binds the coating and helps it set and brown on the head.
- Grated bread
- Forms a crumb crust that crisps and browns in the oven.
- Gravy or turtle sauce
- Supplies moisture and savory flavor that coats the diced meat.
- White wine
- Adds acidity that brightens the rich sauce.
The step that matters
Browning the breadcrumb coating. The egg and crumbs must be fully set and lightly browned before the head is dished. Too little heat leaves the coating pale and soft, while overbaking dries the crust and makes it bitter.
Swap the thyme
How well each one fits the dish's main ingredients (egg, bread, lemon, parsley, sauce, white wine, ketchup):
- Tarragonfits about as well
- Marjoramfits about as well
- Capersfits about as well
- Thymethe original
Fit is the average pairing score against egg, bread, lemon, parsley, sauce, white wine, ketchup. Candidates are from the same food group and used in at least 100 recipes.
