Oatmeal Porridge

Oven, in the book's wordsA gentle oven

Ingredients

Directions

The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. In a brown stew-jar, combine water and oatmeal.

  2. Add salt and let soak for a few hours if possible.

Cook

  1. Cover and cook in a gentle oven at 300°F (150°C) for 2-3 hours.

  2. Alternatively, place the jar in a saucepan of boiling water.

  3. Adjust thickness by adding more oatmeal if cooked for a shorter time.

Serve

  1. Serve on hot plates with desired accompaniments.

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

What each ingredient does

Oatmeal
Its starch thickens the water into a porridge as it cooks slowly.
Water
Hydrates the oats so they soften and swell into a creamy texture.

The step that matters

Long, gentle cooking. Oats need sustained low heat for the starch to gelatinise fully and the grains to soften. Cooking too hot or too briefly can leave the porridge thin, lumpy, or unevenly textured.
