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 ↓
Beef Boll
Ingredients
Directions
Prepare the roll
Cut the beef into slices ½ inch thick.
Mix the sausage meat with the stale bread crumbs and spread this mixture on the beef.
Roll up the beef slices tightly and tie them securely.
Season with salt and pepper, then dredge with flour.
Cook
Place in an earthen dish with the onion, Worcestershire sauce, and tomato ketchup.
Cover with boiling water and cook for 5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Forms the main body of the roll and becomes tender during long, moist cooking.
- Sausage meat
- Adds fat and savory flavor that bastes the beef as it cooks.
- Stale bread crumbs
- Absorb juices and fat from the sausage, helping bind the filling and keep it moist.
- Tomato ketchup
- Adds sweetness and acidity that deepen the savory sauce.
- Worcestershire sauce
- Contributes salty, tangy depth to the cooking liquid.
The step that matters
Cover with boiling water and cook for 5 hours. Long, gentle simmering in liquid breaks down the tough connective tissue in shoulder or shin beef. Water that is too cool or a heat that is too fierce can leave the meat tough or dry.
Swap the onion
How well each one fits the dish's main ingredients (beef, meat, bread, sauce, tomato, ketchup, pepper):
- Capsicumfits better
- Carrotfits about as well
- Onionthe original
- Shallotfits about as well
Fit is the average pairing score against beef, meat, bread, sauce, tomato, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
