Ingredients
Directions
Make the soup
Add rice to boiling salted water and cook until tender.

Beat the egg white and add it to the soup.
Finish with the custard
In a separate bowl, beat the egg yolk with milk.
Slowly add the milk mixture to the soup, stirring constantly to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Cooks into tender grains that give the soup its body and bulk.
- Butter
- Adds richness and a silky mouthfeel to the broth.
- Egg white
- Sets lightly in the hot soup, adding body and a delicate texture.
- Egg yolk
- Thickens the milk mixture and enriches the soup when gently heated.
- Milk
- Adds creaminess and mildness, and dilutes the yolk so it blends smoothly.
The step that matters
Slowly add the milk mixture to the soup, stirring constantly. Egg yolk thickens when heated, but if it meets hot liquid too quickly it scrambles and curdles. Adding it slowly while stirring gently raises its temperature so it blends smoothly into the soup.
