Warabi mochi (Kansai)

Combine warabiko, granulated sugar, and water in a medium saucepan. Stir well with a whisk until the warabiko and granulated sugar are fully dissolved and no lumps remain.

Place the saucepan over medium heat and cook, stirring continuously with a wooden spoon or heat-resistant spatula. The mixture will gradually thicken and become translucent.

Continue stirring vigorously until the mixture is very thick, glossy, and completely translucent, resembling a clear, firm jelly. This process typically takes 8-12 minutes.
