Why it works: Parsley and pepper 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 ↓
Beef Olives
Ingredients
Directions
Prepare the rolls
Place a small piece of fat and a mixture of parsley, bread crumbs, pepper, salt, and egg in each square of steak.
Roll up the meat and tie it securely with string.
Fry the rolls in hot butter or dripping until nicely browned.
Braise and finish
Remove the rolls from the pan and stir in the flour with the remaining butter.
Add enough stock or water to cover the rolls and cook very slowly for 1.5 hours.
Stir in Harvey's sauce and mushroom ketchup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the outer wrapper and becomes tender during slow cooking.
- Bread crumbs
- Absorb moisture from the egg and parsley, giving the filling body.
- Egg
- Binds the bread crumb and parsley filling so it holds together when rolled.
- Flour
- Thickens the cooking liquid into a light gravy.
- Mushroom ketchup
- Adds savoury, umami depth to the sauce.
The step that matters
Cook very slowly for 1.5 hours. Gentle, low heat in liquid breaks down the connective tissue in the steak, making it tender. Fast boiling toughens the meat and can dry out the rolls and loosen the filling.
Swap the parsley
How well each one fits the dish's main ingredients (bread, pepper, egg, butter, flour, sauce, mushroom):
- Parsleythe original
- Capersfits about as well
- Nutmegfits about as well
- Thymefits less well
Fit is the average pairing score against bread, pepper, egg, butter, flour, sauce, mushroom. Candidates are from the same food group and used in at least 100 recipes.
