Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Tenison 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
Cook the steak rare.
Prepare a gravy with butter, pepper, coarse sea salt, flour, and mushroom ketchup.
Cut the steak into small pieces.
Finish and serve
Add the steak to the hot gravy and cover tightly.
Remove from heat or place in a 400°F (200°C) oven for 10 minutes.
Serve with toast and jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Provides the meaty base and main protein of the dish.
- Butter
- Adds richness and fat that carries flavor into the gravy.
- Flour
- Thickens the gravy as its starch swells in the hot liquid.
- Mushroom ketchup
- Adds savory, umami depth to the gravy.
The step that matters
Adding the steak to the gravy. Steak cooked rare keeps cooking when it returns to heat, so it can turn tough and grey if left too long. Covering tightly traps steam and gently warms the meat, which helps keep it tender.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
