Why it works: Shallot and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 376 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
A Rump Steak
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
Cut the steak from the middle of the rump and let it tenderize.
Prepare a warm dish with ketchup and minced shallot or onion.
Cook and serve
Broil the steak at 400°F (200°C), turning it often with steak tongs for 15-20 minutes.
Place the steak on the dish, rub it with butter, and garnish with pickles and horseradish.
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
- Rump steak
- Provides the main meat, cooked through by broiling to a browned, savory surface.
- Ketchup
- Adds sweetness and acidity to the warm dish that the steak rests on.
- Shallot or onion
- Adds mild aromatic sharpness to the base under the steak.
- Butter
- Adds fat and richness to the surface of the cooked steak.
The step that matters
Broiling the steak. Turning the steak often over direct heat helps it brown evenly without drying out. Its surface browns through the Maillard reaction, while the interior stays juicy if it is not overcooked.
