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 ↓
Spanish Eggs
Ingredients
Directions
Prepare the filling
Carefully slit the hard-boiled eggs and remove the yolks.
In a mortar, pound the yolks with equal amounts of cooked veal and ham.
Add chopped parsley, minced shallot, butter, bread crumbs, cayenne, and allspice; mix well.
Fill and fry
Fill the hollowed eggs with the mixture.
Rub the filled eggs with egg yolk.
Fry the eggs in plenty of clean lard or dripping until light brown.
Serve
Serve with anchovy sauce and garnish with slices of hard-boiled eggs or parsley.

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 hollow shells that hold the filling and give the dish its structure.
- Veal
- Adds savory meaty body to the filling, making it firm enough to hold its shape.
- Ham
- Adds salty, savory flavor to the filling alongside the veal.
- Bread crumbs
- Absorb moisture and help bind the filling so it holds together when fried.
- Butter
- Adds richness and fat, giving the filling a softer, smoother texture.
- Egg yolk
- Coats the outside of the filled eggs so they brown evenly when fried.
The step that matters
Frying the filled eggs until light brown. The coating of egg yolk browns in hot fat, and the fat must be hot enough to brown the surface quickly. Frying too long or too hot can darken the coating and dry out or overheat the filling inside.
