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

What each ingredient does

Arrowroot flour
Thickens the liquid into a smooth porridge as its starch swells when heated.
Milk
Adds creaminess and richness, softening the porridge's flavour and texture.
Sugar
Adds sweetness to balance the mild, starchy base.

The step that matters

Stirring constantly while boiling. Arrowroot starch can settle and clump on the bottom of the pan, scorching or leaving lumps. Constant stirring keeps the starch evenly dispersed while it swells and thickens.
