Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Roast Tenderloin of Beef
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.
Roast the beef
Preheat the oven to 350°F (175°C).
Place the tenderloin in a roasting pan and pour boiling water over it.
Roast the tenderloin carefully, basting often with its own juices.
When the tenderloin is nearly done, dredge it with flour and baste once with butter.
Continue cooking for about 10 minutes per pound to achieve rare and juicy meat.
Remove excess fat from the pan.
Make the gravy and serve
Thicken the remaining gravy with browned flour, pepper, and salt.
Bring the gravy to a boil and serve it in a gravy boat with made mustard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef tenderloin
- Forms the main roast; its fat and connective tissue are what keep the meat moist and tender.
- Flour
- Dredged on the surface and browned to help thicken the pan gravy.
- Butter
- Basted over the meat to add fat, moisture and browning to the crust.
- Boiling water
- Poured into the roasting pan to create liquid for the pan juices and gravy.
The step that matters
Continue cooking for about 10 minutes per pound. Tenderloin is lean and cooks quickly, so overcooking dries it out. Timing by weight gives a rare, juicy centre, and checking doneness matters more than the clock.

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