Why it works: Beef and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,971 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Roast a Sirloin of Beef
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beef
Preheat your oven to 400°F (200°C).
Add a little clarified beef dripping to the pan.
Sprinkle salt and black pepper over the sirloin.
Dredge the sirloin with flour and turn it.
Roast and baste
Roast the beef for 15 minutes per pound for medium-rare, or 20 minutes per pound for more well-done.
Baste the beef as soon as it starts to cook.
Baste again every 15 minutes until 20 minutes before it's done.
Once nicely browned, remove from the oven.
Make the gravy
Add hot water to the pan.
Add a little more flour.
Stir until it thickens.

Beef and flour barely smell alike, yet cooks put them together in 10,677 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin of beef
- Is the main cut that is roasted, and its fat and juices make the dish.
- Clarified beef dripping
- Coats the meat and pan, conducting heat and promoting browning on the surface.
- Flour
- Dredged onto the meat and later added to the pan juices, where it thickens the gravy.
The step that matters
Baste again every 15 minutes until 20 minutes before it's done. Regular basting spreads fat and juices over the surface, keeping it moist and encouraging even browning. Stopping 20 minutes early lets the crust set before removal.
