I suggest placing the cooked fritters in the oven at 200ºF/100ºC to keep them warm while cooking the second batch. If you have a lot of zucchini, please double the ingredients. They can be easily heated in an oven toaster or oven. If you don’t want to bother making the yogurt sauce, I think you can eat fritters plain or with gluten-free ketchup.
