2 small zucchini, trimmed and shredded (2 cups)
1 large Idaho or other baking potato, peeled and shredded (2 cups)
1 small yellow onion, finely chopped (1/2 cup)
1/4 cup all-purpose flour
2 large eggs, lightly beaten
2 teaspoons curry powder
1/8 teaspoon salt, or to taste
Ground white pepper
Vegetable oil
Plain lowfat yogurt or sour cream (optional)
Preheat the oven to 200 degrees F. Squeeze as much liquid as possible from the shredded zucchini and potato, then place the vegetables in a large bowl. Add the onion, flour, eggs, and curry powder and stir until well blended. Season with the salt and pepper.
In a large, heavy skillet, heat 1/2" of oil over moderately high heat for 2 minutes, or until very hot. Cook the pancakes in 3 batches, using 3 tablespoons of the batter for each. With a large, metal spatula, flatten each pancake to 1/4" thick. Cook for 3 to 4 minutes on each side, or until crisp and golden.
Using the spatula, transfer the pancakes to a plate lined with paper towels to drain, then to a baking pan. Keep the pancakes warm in the oven. Cook the remaining batter as directed. Stir the batter occasionally and add more oil to the skillet, if needed.
Transfer the pancakes to a serving platter. Garnish with the yogurt, if desired, and serve immediately.
