Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Egg Rissoles
Ingredients
Directions
Prepare the filling
Boil the eggs hard, then peel and separate the yolks from the whites.
Mash the yolks and mix with chopped parsley and lemon juice.
Chop the egg whites finely and add to the yolk mixture.
Shape and fry
Form the mixture into small balls.
Roll the balls in beaten egg and then in breadcrumbs.
Fry in butter or olive oil until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the bulk of the filling, with mashed yolks giving richness and chopped whites adding body.
- Milk
- Adds moisture to the filling so it stays soft rather than dry and crumbly.
- Lemon juice
- Adds acidity that brightens the rich egg flavour.
- Breadcrumbs (in the method)
- Form a crisp, golden coating that browns when fried.
The step that matters
Coating and frying the balls. The beaten egg and breadcrumb coating must be fully set and even, or the balls can break open or soak up oil. Frying over moderate heat lets the coating brown without the outside burning before the filling is heated through.
Swap the parsley
How well each one fits the dish's main ingredients (milk, egg, lemon, butter):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against milk, egg, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
