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

What each ingredient does

Oatmeal
Thickens the water into a creamy porridge as its starch gelatinizes during long simmering.
Milk
Adds moisture and richness, softening the porridge's texture and mellowing its flavor.
Butter
Adds fat for a richer mouthfeel and a rounded, buttery flavor.

The step that matters

Boil slowly for three hours or more until creamy. Oats need a long, gentle simmer for their starches to swell and gelatinize fully. Boiling too hard can scorch the bottom of the pot and make the texture gluey or uneven, so keep the heat low and stir.
