What each ingredient does
- Arrow-root
- Thickens the water into a smooth, clear gruel as it cooks.
The step that matters
Mixing the arrow-root with cold water first. Starch dropped straight into hot liquid clumps, because the outside of each grain gels before the inside can disperse. Blending it smooth in cold water first lets the grains separate so the gruel thickens evenly.
