Ingredients
Directions
Make the broth
Bring 1 gallon of water to a boil in a large pot.
Add 1 tablespoon of coarse sea salt, sliced onions, sweet herbs, celery, and carrots.
Boil gently for 1.5 to 2 hours, then strain the liquid.
Add the rice and finish
Let the broth cool, then for each quart, add 3-4 ounces of rice.
Heat the soup slowly, stirring occasionally, until the rice is tender and the soup thickens.
Season with pepper and stir in 1-2 ounces of butter mixed with 1 teaspoon of flour before serving.
Alternatively, mix in 2-3 egg yolks with a little milk before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Swells and softens as it cooks, thickening the soup and giving it body.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- Flour
- Mixed with butter, it helps thicken the soup slightly as it heats.
- Egg yolks
- Optional; they enrich the soup and add thickness when stirred in gently.
- Onions
- Release sweetness and aroma into the broth during the long gentle boil.
The step that matters
Adding the egg yolks. If egg yolks are added to very hot soup or boiled after mixing, they can scramble and curdle. Stir in a little milk first and keep the soup below a simmer so they thicken it smoothly.
