Why it works: Potato and rice match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
Egg Scallops
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 the filling
Boil the eggs for 20 minutes, then cool and remove the shells.
Chop the eggs roughly and mix them with the mashed potatoes and boiled rice.
Add the capers, vinegar, Worcestershire sauce, pepper, salt, and melted butter. Mix well.
Bake and serve
Spoon the mixture into scallop shells, gem pans, or muffin pans.
Sprinkle bread crumbs on top and add a few bits of butter.
Bake at 400°F (200°C) until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and body, binding the mixture together as it cooks.
- Mashed potatoes
- Add moisture and a soft, tender texture to the filling.
- Boiled rice
- Adds bulk and a light, tender texture to the filling.
- Capers
- Contribute a sharp, briny flavour that cuts through the richness.
- Butter
- Adds fat and richness and helps the topping brown.
The step that matters
Bake until light brown. Baking at 400°F sets the egg and starch mixture and browns the buttered crumbs. Removing it too early leaves the filling soft and pale, while overbaking dries it out and toughens the eggs.

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