Why it works: Pepper and onion 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
In a bowl, combine the finely cut cold fowl with coarse sea salt, black pepper, butter, and onion if desired.
Stir in the 2 fresh eggs until well mixed.
Form the mixture into cakes.
Coat and fry
Dip each cake in beaten egg, then coat with cracker crumbs.
Fry the cakes in boiling lard, a mix of lard and butter, or Ko‑nut until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fowl
- Provides the main body of the croquettes as the bulk of the filling.
- Eggs
- Bind the chopped fowl so the cakes hold their shape when fried.
- Butter
- Adds richness and moisture to the filling and aids browning.
- Cracker crumbs
- Form a crisp, golden outer crust when the cakes are fried.
The step that matters
Frying the cakes in boiling fat. The fat must be hot enough to set the egg and crumb coating quickly, so the crust browns and seals before the cake can break apart or absorb excess oil.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pepper, butter, egg):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against pepper, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
