Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Sirloin 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.
Grill
Preheat a double broiler and oil it well.
Place the steak with the fat edge towards the handle over hot coals.
Cook for about 10 minutes, turning every 10 seconds.
After 40 seconds, move the steak farther from the coals.
Remove the steak to a hot serving dish.
Finish and serve
Dust with salt and pepper, spread lightly with butter, and sprinkle with parsley.
Top with onions, cover, and let stand in a 400°F (200°C) oven for 3-4 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin steak
- Provides the main meat, whose fat edge and thickness shape how it cooks over coals.
- Butter
- Adds richness and moisture to the surface of the hot steak.
- Onions
- Add sweetness and aroma as they soften over the warm steak.
The step that matters
Turning the steak every 10 seconds over hot coals. Frequent turning over intense heat lets the surface brown without burning before the interior cooks through. Letting it sit still can scorch one side while the centre stays underdone.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, parsley):
- Carrotfits better

- Onionthe original
Fit is the average pairing score against pepper, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
