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

What each ingredient does

Mixed flour: Thickens the water into a smooth, starchy gruel as it cooks.
Milk sugar: Adds gentle sweetness to the gruel.
Hot cream: Adds richness and a softer, creamier texture at the end.

The step that matters

Mixing the flour with cold water first. Flour added straight to hot liquid clumps, because the outside of each particle gelatinises before the inside wets. Blending it into cold water first keeps the gruel smooth.
