Why it works: Rice and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 9,645 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
An Edging Fob Hashes
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 rice
Boil the rice in water for 30 minutes.
Season the rice with butter and salt.
Form the rice into a round shape about 3-4 inches high on a dish.
Bake and serve
Brush the top with the egg yolk.
Bake in a 400°F (200°C) oven until browned.
Turn the hash into the center of the dish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the hash, giving it body and a starchy base that holds its shape.
- Butter
- Adds fat and richness, carrying flavor through the rice and helping the surface brown.
- Egg yolk
- Brushed on top, it promotes browning and gives the baked surface a glossy, golden color.
The step that matters
Brush the top with the egg yolk. The yolk coats the surface so it browns evenly in the oven. Spreading it thinly and evenly avoids pale patches or spots that over-brown.
