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 ↓
A Beef Stew
Ingredients
Directions
Prepare
Cut away all fat and skin from the beef and cut it into 2 to 3-inch pieces.
Place the beef in a stewpan and pour in the broth.
Simmer and finish
Bring to a boil, then sprinkle in salt and pepper to taste.
Simmer gently for 2 hours.
Finely shred the lemon and add it to the gravy.
After 20 minutes, mix in Harvey's sauce, lemon juice, flour, and ketchup.
Add Madeira, sherry, or port 15 minutes later and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef rump
- Long, gentle simmering breaks down connective tissue, leaving the meat tender and moist.
- Broth
- Forms the liquid base of the stew and carries the flavour of the dish.
- Flour
- Thickens the cooking liquid into a gravy with body.
- Lemon
- Adds bright acidity and aroma that balance the rich, savoury gravy.
- Madeira, sherry, or port
- Adds depth, sweetness and wine flavour to the finished gravy.
The step that matters
Simmering the beef gently for 2 hours. A rolling boil toughens meat and can leave it dry, while a gentle simmer slowly converts collagen into gelatin, which makes the beef tender and gives the gravy body.

Fit is the average pairing score against beef, pepper, sauce, flour, ketchup, sherry. Candidates are from the same food group and used in at least 100 recipes.
