Grate zucchini: Use a box grater or food processor with coarse blade and grate the zucchini.
Salt the zucchini: Place the grated zucchini in a colander. Sprinkle with ½ teaspoon salt and toss to combine. Let rest for 10 minutes. After 10 minutes
Heat the oven: While the zucchini is resting, heat the oven to 350F. Line a baking sheet with parchment paper.
Drain the zucchini: Working in batches, wrap the zucchini with a clean tea towel and squeeze letting it drain over a large bowl (in case you spill some of the zucchini). Keep on pressing and gently twisting to get out as much liquid as you can. Transfer the zucchini to a large mixing bowl.
Prep the batter: Add in the corn, flour, scallions (or onion), salt, pepper, fresh dill. With a large spoon, combine the dry ingredients together.
Wet ingredients: Add in the egg and milk and stir until it’s all incorporated. Let the batter rest for 5 minutes.
Heat the skillet: If you are frying the fritters, heat the oil in a large skillet over medium heat. As soon as the oil is hot and shimmering, use an ice-cream scooper (or a 1/4 measuring cup or a spoon)and scoop in portions of the batter (I did 4 at a time nicely spaced out). With the spatula, gently flatten slightly. Cook 3-4 minutes per side (until they get a little golden).
Bake fritters: (Optional cooking method without frying)If you are baking the fritters, line up the fritters on the baking sheet. Bake for about 15 minutes, using a spatula to carefully flip them halfway through baking time, or until the edges get nice and crispy (be sure to not get them over brown).
Gently flatten: With the spatula, gently flatten slightly. Fry the fritter, flipping halfway through, about 3-4 minutes a side, or until the outside is golden brown. Don't flip until one side it is beginning to brown or the fritters may not hold together when you flip it.
Fry remainder of fritters: Working in batches and watching carefully, fry the remainder of the fritters until browned and the middle is cooked through, transferring each to a paper towel-lined plate to drain as they finish.
Make the spicy sauce: While the fritters are cooking up, make the sauce
Finish off in oven: Next, once all the fritters are pan fried, transfer them to a parchment lined sheet pan and finish cooking them by baking for about 10-15 minutes 350F oven. The additional baking after frying is optional, but helps crisp the fritters further and they’re all ready to serve warm at once. IF you do not bake them, pan fry them up longer on each side (7-8 minutes).
Serve: Enjoy immediately with our spicy mayo. Or top with your choice of dairy or vegan sour cream or Greek yogurt. (OPTIONAL) Sprinkle with additional paprika and fresh herbs for serving.
