Handle boiling water with extreme care to prevent steam burns or scalds.
In a large measuring pitcher, combine 1 cup rice flour and 1 cup tapioca starch. Add 2 cups room temperature water and 2 cups boiling water. Whisk together for a few minutes until completely smooth with no lumps. Let the batter rest at room temperature for 30 minutes.
Watch out
Whisk thoroughly when adding boiling water to prevent starch clumps from forming prematurely.
