Spinach Loaf

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.

Make the white sauce

  1. Make a thick white sauce by melting oleomargarine in a saucepan.

  2. Stir in flour and cook for a minute.

  3. Gradually add skim milk, stirring constantly until thickened.

Assemble and bake

  1. In a large bowl, mix the white sauce with boiled rice, chopped spinach, and diced red pepper.

  2. Form the mixture into a loaf shape.

  3. Bake in a preheated oven at 350°F (175°C) for 20 to 30 minutes.

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

What each ingredient does

Boiled rice
Provides the bulk and body that hold the loaf together.
Flour
Thickens the milk into a stable sauce that binds the mixture.
Skim milk
Forms the liquid base of the white sauce, adding moisture.
Oleomargarine
Provides fat for cooking the flour and carrying flavor in the sauce.
Chopped spinach
Adds the main vegetable flavor and moisture to the loaf.

The step that matters

Stirring the milk into the roux. Adding milk gradually while stirring constantly keeps the flour evenly dispersed, preventing lumps and producing a smooth sauce that thickens properly and binds the loaf.

Swap the spinach

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

  1. Capsicumfits better
  2. Arrowrootfits about as well
  3. Asparagusfits about as well
  4. Spinachthe original

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