What each ingredient does
- Flour
- Starch that thickens the boiling water into a smooth, porridge-like gruel.
- Sugar
- Adds sweetness to balance the plain, starchy flavour.
The step that matters
Gradually add the flour while stirring. Flour dropped in all at once clumps before its starch can disperse evenly in the hot liquid. Adding it slowly while stirring keeps the particles separate so they hydrate and thicken into a smooth texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
