Ingredients

Directions

Prepare

  1. Cook the tomatoes until tender, then rub them through a sieve.

  2. In the meantime, boil the rice until tender.

Make the soup

  1. Bring the milk to a boil in a separate pot.

  2. Add the butter to the boiling milk, then stir in the tomatoes and rice.

  3. Do not let the mixture boil after adding the tomatoes and rice to prevent curdling.

  4. Season with salt and pepper to taste.

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

What each ingredient does

Tomatoes
Provide the main body, acidity and flavor of the soup.
Rice
Thickens the soup and adds body as it softens and releases starch.
Milk
Adds creaminess and a mild sweetness that softens the tomato's acidity.
Butter
Adds fat for richness and a smoother mouthfeel.

The step that matters

Keep the mixture from boiling after adding the tomatoes and rice. Acid from the tomatoes combined with high heat can make milk proteins clump and curdle, so the soup should be kept hot but below a boil.

Swap the tomato

How well each one fits the dish's main ingredients (rice, milk, butter, pepper):

  1. Potatofits better
  2. Capsicumfits better
  3. Asparagusfits about as well
  4. Tomatothe original

Fit is the average pairing score against rice, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
