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

What each ingredient does

Lentil flour
Starch that thickens the liquid into a smooth, spoonable gruel as it heats.
Water or milk
Liquid that hydrates the flour so its starch can swell and set the texture.
Sugar
Adds sweetness to balance the earthy flavor of the lentils.

The step that matters

Stirring while the gruel cooks until thickened. Lentil starch swells and sets as it heats in liquid. Constant stirring keeps the flour evenly dispersed, preventing lumps and scorching on the bottom of the pot.
