Graham Gruel

Ingredients

Directions

Prepare

  1. In a pot, combine milk and water and heat until just boiling.

  2. In a small bowl, mix graham flour with a little cold water to make a smooth paste.

  3. Stir the paste into the boiling milk and water mixture.

Cook and serve

  1. Reduce heat and let it boil slowly for at least two hours, skimming off any coarse particles that rise.

  2. Season with salt and pepper, and add more milk if desired when serving.

  3. Serve hot with oyster crackers.

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

What each ingredient does

Graham flour
Thickens the liquid into a gruel as its starch swells and gelatinizes during cooking.
Milk
Adds richness and body, and its proteins and sugars contribute to a creamier texture.

The step that matters

Simmering slowly for at least two hours. Gentle, prolonged simmering lets the flour's starch fully swell and soften so the gruel turns smooth rather than pasty. Skimming removes coarse bran particles that would otherwise stay gritty. Boiling too hard can scorch the milk on the bottom of the pot and make the surface form a skin.
