Start with the grated zucchini in a sieve and salt liberally, mix the salt through. Let is sit in the sieve for a few minutes before squeezing out as much water from the zucchini as you can with gumption.
If you have time, caramelise your onion by frying it on low heat in a pan with some olive oil until delicious, soft and brown. This step can take 30 minutes, so definitely optional, the raw onion mixed it will do just fine!
In a bowl, mix the zucchini in with all the other ingredients.
In a pan, heat a glug of olive oil and shape the fritter mixture into 5 little patties.
Fry for 3-5 minutes each side, or until cooked through and golden on the outside.
