Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs: Set to form a soft filling inside each pepper half when baked.
Breadcrumbs: Absorb butter and soak up moisture, giving the filling a light, crisp-edged texture.
Grated ham: Adds savory, salty flavor to the filling.
Butter: Adds richness and helps the breadcrumbs brown and taste savory.
Green peppers: Hold the filling in place and add a mild, slightly bitter vegetable flavor.

The step that matters

Bake until the egg white is set. Egg whites set at about 60 to 70°C while yolks stay runny at lower heat, so the white should be firm and opaque before removing from the oven. Underbaking leaves raw white; overbaking makes the yolk chalky and rubbery.
