Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Prepare the mixture
Combine oysters, veal, butter, cracker crumbs, egg yolks, onion juice, salt, and pepper in a bowl.

Dip each roll in beaten egg, then coat with cracker crumbs.
Fry the rolls quickly until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and moisture of the filling.
- Veal
- Adds body and bulk to the filling, giving it a meaty texture.
- Egg yolks
- Bind the filling so the rolls hold their shape.
- Cracker crumbs
- Absorb moisture and help the mixture set firm enough to shape.
- Butter
- Adds richness and softness to the filling.
The step that matters
Frying the rolls quickly. Frying over high heat browns the crumb coating fast while the filling stays moist inside. Frying too slowly lets the coating soak up oil and the oyster filling overcook or leak out.
Swap the onion
