Using the big holes on your box grater, shred all zucchini. Wrap in a kitchen towel and squeeze hard to get rid of extra water.

Crack and whisk eggs in a big bowl. Throw in your shredded zucchini, sliced scallions, grated garlic, chopped dill, lemon peel, salt, and a few twists of pepper. Stir in 1½ cups panko and sprinkle flour over top, then fold everything together. Put the other ¾ cup panko in a flat dish nearby.

Get your cast-iron pan warming up over medium heat. Scoop the zucchini mix with a ¼-cup measure, making 14 to 16 flat rounds. Roll each one in the panko you set aside until fully covered. Don't worry if they seem a bit soft - they'll firm up when cooked.

Add plenty of oil to your hot skillet. Cook each round for 2 to 3 minutes, flip them over, then cook another 2 to 3 minutes until they're nice and brown on both sides. You'll probably need to cook in batches. Put cooked rounds on paper towels to soak up extra oil.

Add a bit more salt if needed and serve with your choice of tartar sauce or creamy dill sauce.
