Using a box grater or food processor, grate zucchini and place in colander. Sprinkle with sea salt and stir well. Place colander in sink and allow to sit for 10 minutes.
While zucchini sits, prepare other ingredients:
Zest the lemon. Use a fork to combine cheese and lemon zest, set aside. Whisk the egg and chop the chives
After zucchini rests, place between paper towels and squeeze out excess moisture (or wring out in a clean dish towel) The more moisture you eliminate the crispier your fritter will be, so squeeze!
Place zucchini in a large bowl.
Add egg, your choice of flour, arrowroot or cornstarch, pepper, lemon zest and 3 tablespoons of chives (reserving one 1 T for garnish). Mix well.
Take a third of a cup at a time and form into patties with hands
Heat a pan on high heat for one minute. Add 1 Tablespoon butter or olive oil, coat pan evenly. When butter or oil is very hot add zucchini patties. Turn heat to medium high.
Cook until golden brown (about 3-4 minutes) gently turn.
Cook second side until golden brown. (turn down heat if needed)
Work in batches, carefully wiping down pan between and adding more butter or oil for next batch.
Top with lemon ricotta. Garnish with remaining chives. Serve
