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 ↓
Parisienne Eggs
Ingredients
Directions
Prepare
Slice the hard‑boiled eggs thinly and season with paprika, salt, parsley, and onion juice.
Dip the egg slices in grated Parmesan cheese.
Butter a baking dish and line it with seasoned sliced tomatoes.
For the cream sauce, combine heavy cream, Parmesan cheese, cayenne pepper, salt, French mustard, English mustard, and lemon juice.
Assemble and bake
Cover the tomatoes with a cream sauce, then add a layer of eggs, followed by more sauce, repeating until the dish is filled.
Make the last layer of sauce decorative by forcing it through a tube.
Garnish the dish with potato balls.
Heat the dish in the oven until warmed through and browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled eggs
- Form the main layers, giving the dish its body and substance.
- Heavy cream
- Forms the rich sauce that moistens the layers and sets when heated.
- Parmesan cheese
- Adds savoury flavour and helps the sauce brown in the oven.
- English mustard
- Adds sharp pungency that cuts through the richness of the cream.
- Sliced tomatoes
- Add moisture and acidity to the base layer.
The step that matters
Heating the assembled dish. Heat must warm the eggs and set the cream sauce without boiling it, since overheated cream can separate and turn grainy. Stop once the top is golden.
Swap the onion
How well each one fits the dish's main ingredients (egg, parsley, parmesan cheese, cream, pepper, mustard, lemon):
- Spinachfits better
- Broccolifits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, parsley, parmesan cheese, cream, pepper, mustard, lemon. Candidates are from the same food group and used in at least 100 recipes.
