To a large mixing bowl, add all ingredients for kofta including mashed potatoes, grated paneer, finely chopped ginger, cilantro, green chili, cashews, raisins, cornstarch, salt, white pepper powder and 1/4 teaspoon cardamom powder.
Mix ingredients together with your hands to form a dough. Make koftas from the dough by taking some dough between your hands and rolling between your palms to make it round like a meatball. Make koftas until there is no more dough.
Heat enough oil to fry in a wok on medium-high heat. Make sure oil is hot, or koftas will stick to the pan.
Drop koftas in hot oil and fry until golden brown on both sides. Remove the fried koftas an let rest on a paper towel.
To serve, pour curry gravy on a serving plate and drizzle with cream and sprinkle with chopped cilantro.
