To make the sauce, in a food processor or blender add all the ingredients and blend until smooth.
To make the fritters, start with the grated zucchini sprinkling a 1/2 teaspoon of salt, and add to a paper towel or dish towel. Let the grated zucchini sit for 10 minutes before squeezing as much water as you can out.
To a large bowl add all the ingredients to the bowl except the oil for frying. Stir until a batter is formed and let it sit for 5-10 minutes.
On the stove preheat a saute pan over medium-high heat with 1-2 tablespoons of oil
Scoop about 2-3 tablespoons of batter into the preheated pan with oil and press into a thin pattie, fitting about 3-4 in the pan
Fry each side until golden brown for about 5-6 minutes each
Reheat more oil as needed in between each round of cooking the fritters
Plate the fritters with a dollop of the preserved lemon sauce
