Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Ragout of Eggs and Bacon
Ingredients
Directions
Prepare the eggs
Boil the eggs for 10 minutes.
Transfer the eggs to cold water.
Peel the eggs.
Cut them in half.
Make the filling
In a bowl, pound the yolks with the shredded chicken or veal, parsley, anchovy, shallot, butter, mushroom ketchup, cayenne, bread crumbs, and mace or allspice until well combined.
Fill and brown
Fill the egg white halves with the mixture.
Brush the filled eggs with beaten egg yolk.
Brown them in a Dutch oven.
Serve on a bed of crispy bacon or ham.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish, with yolks binding the filling and whites holding it.
- Cooked chicken or veal
- Adds savory body and substance to the filling.
- Butter
- Adds fat and richness, giving the filling a smooth, moist texture.
- Bread crumbs
- Absorb moisture and help the filling hold together with a soft texture.
- Anchovy
- Adds deep savory flavor that enriches the filling without tasting distinctly fishy.
- Mushroom ketchup
- Contributes concentrated savory, umami flavor to the filling.
The step that matters
Brown them in a Dutch oven. Browning sets the surface and develops color and flavor through the Maillard reaction. Too little heat or time leaves the coating pale and underdeveloped, while too much can scorch the egg-yolk glaze.
Swap the parsley
How well each one fits the dish's main ingredients (egg, chicken, anchovy, shallot, butter, mushroom, ketchup):
- Capersfits better
- Thymefits about as well
- Parsleythe original
- Tarragonfits about as well
Fit is the average pairing score against egg, chicken, anchovy, shallot, butter, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
