Why it works: Ketchup and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
Prepare the filling
Mix parsley, bread crumbs, egg yolk, and seasoning in a bowl.
Cut the fat from the steak into small pieces and mix with the force-meat.
Roll and brown
Cut the steak into squares about 2 inches wide and ½ inch thick.
Place a small amount of the force-meat in each square and roll them up, tying with string.
Dip each roll in flour, then season with salt and pepper.
Brown the rolls quickly in butter.
Braise
Place the browned rolls in a stewpan, add stock and sauces, skim when boiling.
Cook slowly for 1.5 hours.

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 provides the meaty flavour of the dish.
- Bread crumbs
- Absorb moisture and give the filling a soft, binding body.
- Egg yolk
- Binds the filling together and adds richness.
- Flour
- Dusting on the rolls helps them brown and thickens the cooking liquid.
- Mushroom ketchup
- Adds savoury, umami depth to the stock and sauce.
The step that matters
Browning the rolls quickly in butter. Searing the outside creates browned flavour through the Maillard reaction and seals the surface. Browning too slowly or too long can dry the thin steak before the slow braise begins.
Swap the parsley
How well each one fits the dish's main ingredients (bread, mushroom, ketchup, sauce, egg, flour, pepper):
- Capersfits about as well
- Parsleythe original
- Nutmegfits about as well
- Marjoramfits about as well
Fit is the average pairing score against bread, mushroom, ketchup, sauce, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
