Why it works: Ketchup and sauce 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 ↓
Welsh Stew
Ingredients
Directions
Braise the beef
Combine beef and broth in a large pot. Bring to a boil, then reduce to a simmer for 1 hour.
Add leeks or onions, turnips, sugar, white pepper, and salt. Simmer for 1¼ to 1½ hours.
Keep the stew simmering.
Thicken and finish
In a small bowl, mix rice flour with mushroom ketchup, lemon juice, and soy sauce until smooth.
Stir the mixture into the stew with grated lemon rind. Cook for 15 minutes.
Add port or white wine before serving, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef rump
- Supplies the meat that becomes tender during long, slow simmering.
- Rice flour
- Thickens the stew broth into a smooth, lightly body-rich sauce.
- Leeks or onions
- Add sweetness and savory body as they soften in the broth.
- Turnips
- Add mild earthy flavor and soft texture after long simmering.
- Mushroom ketchup
- Adds deep savory, umami flavor to the broth.
- Lemon rind and juice
- Add bright acidity and aroma that balance the rich meat and broth.
The step that matters
Keep the stew at a gentle simmer. A rolling boil toughens meat proteins and can break up the vegetables, while a gentle simmer slowly breaks down connective tissue so the beef becomes tender and the broth stays clear.
Swap the lemon
How well each one fits the dish's main ingredients (beef, pepper, rice, flour, mushroom, ketchup, sauce):
- Limefits about as well
- Avocadofits about as well
- Lemonthe original
- Coconutfits less well
Fit is the average pairing score against beef, pepper, rice, flour, mushroom, ketchup, sauce. Candidates are from the same food group and used in at least 100 recipes.
