Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Sirloin of Beef En Epigram
Ingredients
Directions
Prepare the beef
Roast the sirloin of beef and remove it from the spit.
Lift off the skin carefully.
Cut out the lean part of the beef, avoiding the ends and sides.

Make the sauce and finish
In a saucepan, combine the gravy, chopped onion, ketchup, pepper, salt, sliced cucumbers, and a little butter mixed with flour.
Add the meat to the pan and toss for five minutes.
Place the meat back on the sirloin.
Cover the meat with the skin.
Serve garnished with horseradish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin of beef
- Provides the main meat, whose lean cut is cubed and returned to the joint.
- Gravy
- Supplies liquid and savoury body for the sauce the meat is tossed in.
- Butter mixed with flour
- Flour thickens the sauce while butter adds richness and smooth texture.
- Pickled cucumbers
- Adds sharp acidity that cuts through the richness of the beef and gravy.
- Onion
- Adds savoury aroma and sweetness as it cooks into the sauce.
The step that matters
Toss the meat in the sauce for five minutes. Brief heating in the thickened sauce warms the beef through without toughening it. Overcooking dries the lean meat and can make the flour-thickened sauce break or turn gluey, so keep the time short and the heat gentle.
Swap the cucumber
How well each one fits the dish's main ingredients (beef, onion, ketchup, pepper, butter, flour, horse):
- Mustardfits better
