Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Stuffed Eggs
Ingredients
Directions
Prepare the eggs
Place the eggs in cold water, bring them to a boil, and simmer the eggs for 20 minutes.
Transfer the eggs to cold water and peel the shells off.
Cut the eggs in half lengthwise and remove the yolks.
Stuff and shape
Mash the yolks and mix in the sardines, salt, pepper, mustard, lemon juice, and melted butter.
Press the mixture back into the egg whites and fit the halves together.
Secure the halves with toothpicks.
Coat and fry
Dip the stuffed eggs in the beaten egg mixed with water.
Roll the eggs in bread crumbs.
Fry the eggs in deep hot fat until golden brown.
Drain the eggs on paper and remove the toothpicks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites set firm to hold the yolk filling, and the yolks become the creamy stuffing.
- Sardines
- Add savory, salty flavor and richness to the yolk filling.
- Butter
- Adds richness and moisture to the mashed yolk filling.
- Bread crumbs
- Form a crisp, golden browned coating when fried.
- Lemon juice
- Adds acidity that brightens the rich sardine and yolk filling.
The step that matters
Fry the eggs in deep hot fat until golden brown. Fat that is not hot enough lets the breaded coating absorb oil and turn greasy before it crisps. Hot fat sets the crumb quickly into a crisp shell while the filling stays soft and warm inside.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, lemon, butter, bread, tomato, sauce):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Mustardthe original
Fit is the average pairing score against egg, pepper, lemon, butter, bread, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
