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

What each ingredient does

Zucchini (in the method): Forms the edible boat that holds the filling while it cooks.
Rice: Absorbs the milk and swells, giving the filling body and bulk.
Hard boiled eggs: Add richness and a firm, creamy texture to the filling.
Milk: Hydrates the rice as it simmers, helping it soften and swell.
Sour cream: Adds moisture and tang to the sauce that surrounds the zucchini.
Flour: Dry coating on the filled zucchini that helps promote browning when fried.

The step that matters

Simmer the rice in milk until it starts to swell. Rice that is undercooked stays firm and gritty inside the zucchini, while overcooked rice turns mushy and loses its shape. Stopping when the grains just begin to swell gives a tender filling that holds together during baking.
