Grate the potatoes then rinse and pat dry with kitchen paper. Place into a medium bowl and combine with garlic, egg, baking powder, flour, parsley, mint and cumin. Season with salt and pepper. Mix well.
In a large frying pan heat a generous amount of oil over medium heat. Spoon 2 tablespoons of potato mixture into the pan and flatten with a spatula. Fry until golden brown on the bottom, flip and fry on the other side. Place onto a plate lined with kitchen paper and repeat with the rest of the potato mixture. Serve hot.
