1 large russet potato, cut into ½ inch cubes (2 cups)
Bring ¼ cup of water to a boil in a large skillet. Add the onions, garlic, and ginger; cook over medium-low heat for 10 minutes or until onions are starting to turn golden, stirring occasionally and adding additional water, 1 to 2 tablespoons at a time, as needed to prevent sticking. Stir in the tomatoes, curry, coriander, cumin, turmeric, cayenne, and black pepper. Cook for 10 minutes more or until tomatoes are softened, stirring occasionally.
