1 1/2 c white rice flour plus more for rolling
3/4 c tapioca starch
1 T baking powder
1 tsp fine sea salt
6 T cold unsalted butter cut into pieces
3/4 c skim milk
Preheat oven to 400F. Line a baking sheet with a silicone mat or parchment paper. Whisk together flour, starch, baking powder and salt. Cut in the butter with a pastry cutter or two knives. Make sure you leave some larger pieces of butter in the mixture. Add the milk starting with a 1/2 c at a time mixing until the dough comes together. Put some flour on your work surface and dump out the dough. Knead a few times and then roll it out to 1/2 inch thickness. Cut into biscuits using a biscuit cutter. You can gently reform the dough to make additional biscuits. Bake for 15-20 minutes until lightly browned. Serve warm.
