This recipe was posted in our local newspaper, and my husband and I thought it sounded good. The recipe is very user friendly with the most work being the shredding of the zucchini and the potato. The work is well worth it though--trust me!
Shred the zucchini into a bowl using the large holes of a box grater. Place the grated zucchini in a medium bowl and sprinkle with 1/2 to 1 teaspoon kosher salt. Transfer zucchini to a colander in a bowl and let zucchini drain at least 15 minutes and up to 30 minutes. Using your hands or a towel, squeeze out the excess liquid.
Shred the potato into a bowl using the large holes of a box grater.
In a bowl, mix together the onion, egg, and flour, and pepper to taste. Add zucchini and potatoes; mix well. Work quickly because the zucchini-potato mixture oxidizes and discolors once hit by the fresh air.
Heat 2 to 4 tablespoons of the oil in a large skillet over medium-low heat. When the pan is hot enough to create a small sizzle, ladle the mixture into the pan to form six 4-inch cakes. Fry until golden on the bottom, 7 to 10 minutes. Using a spatula, turn the pancakes over until browned on the second side, about 6 minutes longer.
