Mix grated potatoes, grated carrots, minced ginger, minced garlic, finely chopped Serrano, Red pepper flakes, Ground Black pepper, Lemon juice, Chopped cilantro, and some salt using a spatula in a large mixing water.
Add Chickpea flour and mix well until all the moisture released has been absorbed. Cover with plastic wrap and refrigerate for about 30 min
Take a non-stick skillet and grease it with some Olive Oil. Put it on medium high heat. Make small balls with your hands and fry them. Do not fry all at once. Fry the fritters in batches for even browning and crispiness.
Use your spoon or a wooden spatula to press the center of the fritters. It will spread out and expand in width. Do it as soon as you place them in the pan. If you want a thick fritter then you'll have to fry for a longer time. Toss it over and fry the other side. Fry it until you see golden-brown crust on both sides. Cook for about 2-3 minutes per side. Be careful with hot oil.
Garnish with fresh cilantro or parsley and serve with vegan Sour cream or tomato ketchup.
