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 ↓

Ingredients
Directions
Prepare the rolls
Cut the beef into pieces about 3 by 4 inches.
Sprinkle the beef with salt and pepper.
Cover one side with minced onion and place a piece of bacon on top.
Roll the beef tightly and secure with toothpicks or tie with cord.
Brown and braise
Brown the rolls in a hot frying pan with melted lard or bacon fat.
Pour in boiling water until it covers the meat.
Cover the pan and cook slowly for about 2 hours until the meat is tender.
Finish the gravy
Thicken the gravy with a little flour before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Forms the main body of the rolls and becomes tender during slow cooking.
- Bacon
- Adds fat and smoky savour that flavours the meat as it cooks.
- Onion
- Adds aromatic sweetness and moisture that softens as it cooks inside the roll.
- Flour
- Thickens the cooking liquid into a gravy.
The step that matters
Browning the rolls. Searing the outside in hot fat builds browned, savoury flavour through the Maillard reaction. Pale rolls taste flatter, and the gravy will lack depth.

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