1 In a sieve set over the sink or a bowl, combine potatoes, sweet potato, and onion.2 Using your hands, firmly squeeze handfuls of grated potatoes to remove as much liquid as possible.3 Transfer to a large bowl and add rice, eggs, brown rice flour, baking powder and salt. Mix well.4 Preheat oven to 250F (120 C).5 In a large, wide skillet, over medium-high heat, heat just enough canola oil to cover the bottom of the pan in a thin layer.6 In batches, using 2 Tbsp (30 mL) of the mixture per latke, drop latkes about 1 inch (2.5 cm) apart in pan.7 Flatten to 1/4-inch (0.5 cm) thickness with the back of a spoon.8 Repeat with remaining mixture, adding canola oil and reheating pan between batches as needed. Serve hot.
