Grate zucchini and sprinkle with salt. Combine well and place in a strainer or colander to drain. Place in fridge for 30 minutes, or longer if possible, then pour off any excess liquid.
Place the drained zucchini in a large bowl adding the onion, garlic, eggs, coriander, plain flour and ricotta. Stir gently until just combined.
Heat oil in a non-stick fry pan over a medium heat. Drop heaped dessertspoons of batter into the pan and cook for approximately 3 minutes until browned. Flip and repeat until cooked.
Serve fritters with smoked salmon and lightly fried cherry tomatoes. Toast and avocado slices are also a lovely addition to this dish.
