Grate potatoes into in colander set in sink. Take double handfuls and press to squeeze out excess liquid. Transfer to bowl.
Add chives, onion, and cashew cream, and stir to combine.
Heat oven to 200. Place paper towels on plate and set next to stove.
Add enough oil to frying pan to just cover the bottom and heat until a drop of water dropped on it sizzles. Drop heaping spoonfuls of batter onto pan to form small pancakes. Use the spatula to push any stray bits of potato back into the pancake, then press each pancake to flatten.
Fry 3-4 minutes until brown and crisp, turn, and repeat. Place latkes on paper towels, lightly sprinkle with salt and pepper, and keep warm in the oven.
Repeat with remaining potatoes, adding more oil to pan as needed.
