Ingredients

Directions

  1. Boil the rice in 5 cups of water with the butter, pepper, and salt until tender.

  2. Once soft, add the tomato juice and cheese.

  3. Stir until the soup boils and the cheese has dissolved.

  4. If too much water has evaporated, add a little more.

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

What each ingredient does

Rice
Provides the body of the soup as its starch softens and thickens the liquid.
Grated cheese
Melts into the broth, adding richness, savoury flavour and a creamy texture.
Tomato juice
Adds acidity, colour and a tangy flavour to the broth.
Butter
Adds fat, which carries flavour and gives the soup a smoother mouthfeel.

The step that matters

Melting the cheese. Cheese is best added to a gently boiling liquid and stirred until it melts. Overheating or adding it without stirring can make it grainy, stringy or clump instead of blending smoothly into the broth.

Swap the tomato

  4. Asparagusfits about as well

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