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 ↓
Tenderloin Steak and Mushrooms
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Place the tenderloin steaks in a well‑buttered dripping pan, ensuring they do not touch each other.
Add 1 cup of boiling water to the pan and cook for 30 minutes, basting often.
Finish and serve
Ten minutes before serving, remove from the oven and season with salt and pepper.
Top each steak with a small slice of onion and a thin slice of tomato.
Pour a little melted butter over the steaks and return to the oven.
Heat the can of French mushrooms in their own liquid, drain, and place on top of the steaks along with the drippings.
Garnish with parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tenderloin steaks
- The main protein, cooked gently in buttered pan with water to stay moist and tender.
- Butter
- Adds richness and helps the steaks brown and carry flavour in the pan.
- French mushrooms
- Add savoury, earthy flavour and moisture over the steaks as they finish.
The step that matters
Ten minutes before serving, remove from the oven and season with salt and pepper.. Salt seasons the surface and dissolves into the juices. Timing the seasoning near the end keeps the steaks from drawing out moisture during the long braising-style cook.
Swap the onion
