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 ↓
Hashed Beef
Ingredients
Directions
Prepare
Cut the beef into small thin slices and place on a plate.
Add flour, chopped onion, salt, and pepper to the beef and mix well.
Cook
Put the mixture into a saucepan with water and stir over heat until just boiling.
Reduce heat and let it simmer for 10 minutes before serving.
For improved appearance, add brown gravy or coloring, and for flavor, include herbs or catsup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cooking liquid into a gravy-like sauce that coats the beef.
- Onion
- Adds savoury aromatic flavour that deepens the taste of the sauce.
- Cooked beef
- Provides the main body and meaty flavour of the dish.
The step that matters
Stirring until just boiling, then simmering gently. Flour needs to be heated and dispersed evenly in the liquid to thicken properly without lumps. Once boiling, lowering the heat to a gentle simmer keeps the beef tender rather than tough and dry.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (beef, flour, onion, pepper):
- Turmericfits better
- Garlicfits better
- Cuminfits about as well
- Parsleythe original
Fit is the average pairing score against beef, flour, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
