Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Cook the rice until done.

Fry, season and bake

  1. Fry the rice and onion in lard until the onion is light brown.

  2. Add the tomatoes, stock, salt, and pepper.

  3. Stir well and bake in the oven at 350°F (175°C) for about 45 minutes.

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

What each ingredient does

Rice
Forms the body of the dish, absorbing the tomato and stock liquid as it bakes.
Chopped onions
Adds savory sweetness and aroma as they brown in the fat.
Cooked tomatoes
Provide moisture, acidity and color that flavor the rice.
Lard
Fat for frying that coats the grains and carries flavor from the onion.
Beef stock
Supplies the liquid that the rice absorbs while baking.

The step that matters

Fry the rice and onion in lard until the onion is light brown. Browning the onion and toasting the rice in fat builds savory flavor through browning and coats the grains, helping them stay separate rather than clumping.

Swap the onion

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

  4. Onionthe original

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