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 ↓
Braised Spare Ribs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and brown
Cut the spare ribs into portions by cutting between every other rib.
Place the ribs in a roasting pan and bake in a 400°F (200°C) oven until nicely browned.
Make the gravy
Make a gravy by adding the brown stock, minced onion, sage, celery, ketchup, and Worcestershire sauce.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spare ribs
- Provide the main meat, which browns in the oven to develop rich savory flavor.
- Brown stock
- Forms the liquid base of the gravy, adding moisture and savory depth.
- Ketchup
- Adds sweetness and acidity to the gravy, balancing its savory notes.
- Worcestershire sauce
- Adds savory, tangy depth to the gravy.
The step that matters
Browning the ribs in the oven. Ribs that are not browned well stay pale and taste flat, because browning comes from the Maillard reaction between surface proteins and sugars at high heat. Cook until the surfaces are deep golden, not just heated through.
Swap the sage
How well each one fits the dish's main ingredients (onion, celery, ketchup, sauce):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Sagethe original
Fit is the average pairing score against onion, celery, ketchup, sauce. Candidates are from the same food group and used in at least 100 recipes.
