Why it works: Shallot and parsley 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, Gratin Style
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the egg yolks, bread crumbs, butter, anchovies, shallot, parsley, pepper, and salt until well combined.
Spread the mixture over the bottom of a gratin dish.
Bake and serve
Bake in the oven until slightly browned.
Remove from the oven and carefully break the eggs into the dish.
Season the eggs to taste and return to the oven for a few minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the mixture and add richness to the base layer.
- Bread crumbs
- Absorb the butter and yolks, giving the base a light, soft body.
- Butter
- Adds fat for richness and helps the base brown in the oven.
- Anchovies
- Add a salty, savoury depth that seasons the base.
- Eggs
- Set in the oven on top of the base to form the main dish.
The step that matters
Returning the eggs to the oven. Whole eggs set from the outside in, so the whites firm before the yolks thicken. Watching closely for a few minutes avoids overcooked, rubbery whites or runny yolks.
Swap the shallot

Fit is the average pairing score against egg, bread, butter, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
