Add the flour into a large bowl and make a well in the middle, crack in the egg and whisk it, then add in the sparkling water and whisk everything together until you get a smooth batter
Once you end up with a smooth batter, add in the chopped onion, grated garlic, chopped parsley, shredded carrots, grated cheese, rosemary, thyme, and season with sea salt & black pepper, mix together until well mixed
Heat a large fry pan with a medium heat and add in the sunflower oil
After a couple of minutes start adding in spoonfuls of the batter, making sure they're all in a single layer and evenly spaced out, cook in batches to not over crowd the pan, fry for 5 minutes per side or until golden and crispy, transfer into a dish with paper towels as you finish each batch
To make the dipping sauce, add the Greek yogurt into a bowl, along with the grated garlic, dried dill, lemon juice, and olive oil, then season with sea salt & black pepper and whisk together until you get a creamy sauce
Transfer the yogurt sauce into a serving dish and decorate the fritters around it, serve warm or at room temperature, enjoy!
