Ingredients

2 large potatoes peeled, grated and squeezed dry (about 1 1/2 lbs.)
1 medium yellow onion, chopped (about 1 1/4 cups)
1/4 cup flour
1 tsp. baking powder
1/4 cup canola oil, divided, for frying

Preparation
1. Combine all ingredients in large bowl. Heat 1 Tbs. oil in large skillet over medium heat. Scoop 1/2 cup potato mixture into skillet and spread into 1/8-inch thick patty. Repeat. Fry patties 3 to 4 minutes per side, or until golden brown. Cook remaining latkes in batches of 2, adding 1 Tbs. oil to skillet each time.

2. To drain, transfer latkes to wire rack on top of baking sheet lined with newspaper. Place latkes on pan in oven to keep warm. Serve with vegan sour cream or applesauce.
