Salt and drain zucchini: Salt the grated zucchini with about 1 teaspoon of salt. Place in a sieve or colander over a bowl. Let sit for 10 minutes.

Press down with a wooden spoon to push out more of the water. Wrap in paper towels and try to squeeze out more liquid.

Make dipping sauce: While the zucchini is releasing its liquid in step one, make the dipping sauce. Whisk together the sour cream, minced garlic, lemon zest, lemon juice, and a pinch of salt into a medium bowl and set aside.

Mix zucchini with egg, flour, green onions, herbs, zest, salt, pepper: Whisk egg in a large bowl. Add the grated zucchini, flour, minced green onions, thyme, basil, lemon zest, salt and pepper. Mix to combine well.

Fry zucchini fritters: Heat oil in a large skillet (we recommend a 10-inch cast iron skillet) over medium high heat until the oil is shimmery and hot. Test the oil by flicking a little flour into it. If the flour sizzles it's ready.

Cook the fritters in batches. Drop heaping tablespoons of batter into the skillet. Flatten slightly with the back end of a spoon or spatula. Cook, turning once, until browned, 4-6 minutes on each side.

Transfer to a paper towel-lined plate. Sprinkle with salt. Repeat with remaining batter.

Serve immediately, with sour cream dipping sauce.

Fritters can be reheated by placing on a sheet pan under a broiler for a minute or two.
