Blend the cashew and milk together until you get a thick creamy cashew milk. Feel free to strain out the cashew particles for a smoother milk and set aside
In the same wok as before, heat 2 tbsp of ghee for about 30 seconds on medium heat and add in the cumin seeds. Once they start to splutter, add in the chopped onions and cook down until slightly browned for about 4-5 minutes
Add in the cumin powder, coriander powder, haldi, red chili powder and salt and mix thoroughly and cook the spices with the onions for another 3-4 minutes or until onions are browned
Add the blended spinach mixture to the onions followed by the cashew milk and mix all ingredients together. You should have a beautiful green creamy mixture at this point. Reduce the heat to medium low
Cook the palak mixture for 2 minutes and add the grated paneer. Thoroughly mix the grated paneer with the palak to ensure it is all coated evenly and cook on low heat for 5-6 minutes until the paneer is cooked
