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 ↓
Eggs and Bacon Ragout
Ingredients
Directions
Prepare the eggs
Boil the eggs for 10 minutes, then transfer them to cold water.
Peel the eggs and cut them in half.
Make and fill
In a bowl, pound the yolks with the chopped fowl or veal, parsley, anchovy, shallot, butter, mushroom ketchup, cayenne, bread crumbs, and allspice until well combined.
Fill the egg white halves with the mixture.
Brown and serve
Brush the filled eggs with beaten egg yolk and brown them in a Dutch oven.
Serve the eggs 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 structure of the dish, with whites holding the filling and yolks blended into it.
- Cooked fowl or veal
- Adds savory meaty body and richness to the filling.
- Bread crumbs
- Absorb moisture and help the filling hold a soft, spreadable texture.
- Butter
- Adds fat for richness and a smoother, silkier filling texture.
- Anchovy
- Contributes deep savory flavor that enhances the umami of the filling.
The step that matters
Browning the filled eggs. Brushing with beaten yolk and browning in a Dutch oven gives color and a glossy surface. Browning happens through the Maillard reaction, which needs dry, fairly high heat, so the eggs should be watched to avoid scorching or drying out.
Swap the parsley
How well each one fits the dish's main ingredients (egg, veal, anchovy, shallot, butter, mushroom, ketchup):
- Capersfits better
- Parsleythe original
- Thymefits about as well
- Tarragonfits about as well
Fit is the average pairing score against egg, veal, anchovy, shallot, butter, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
