Using a box grater, finely shred the potatoes and onion, then add the shredded ingredients over a cheesecloth and squeeze all the water out

Add the flour and baking powder into a large bowl, mix together, then make a well in the middle, crack in the egg and whisk the egg, and then add in the club soda and whisk everything together until you get a smooth batter

Add the shredded potatoes and onion over the batter, along with the chopped garlic, sweet smoked paprika, chopped chives, and season with salt & pepper, mix together until well mixed

Heat a large fry pan with a medium heat and add in the olive oil

After a couple of minutes and the oil is nice and hot, start adding in spoonfuls of the batter and gently pushing down on each one, you want all the fritters in a single layer and evenly spaced, so cook in batches to not overcrowd the pan, fry for 4 minutes per side or until golden and crispy, then transfer into a dish with paper towels

To make the spicy yogurt sauce, add the Greek yogurt into a bowl, along with the grated garlic, hot smoked paprika, lemon juice, olive oil, and season with salt & pepper, whisk together

Transfer the yogurt sauce into a serving dish and decorate the fritters around it, garnish with chopped chives, enjoy!
