Preparing The Spinach: Always use fresh spinach and completely avoid using matured spinach as it can spoil the taste of the whole preparation. Avoid using the stalk as well.
I like to use baby spinach for Palak Paneer preparation. Rinse them properly under running water and keep them in a bowl with lukewarm water and a bit of salt for 15 minutes or so to get rid of the pesticides. Get rid of the water and again rinse them under running water.
Blanch the Spinach: Prepare a pot of water to a boiling point. Add the chopped spinach leaves and blanch for 2 minutes. Add about 1/2 tsp of salt to it.Drain and immediately transfer the spinach to a bowl of ice water to stop the cooking process, keeping that vibrant green color. Drain again and set aside.
Before setting it aside make sure you get rid of the water from the spinach properly, use a strainer, and later on squeeze them to get rid of the excess water in them.
Prepare the Paneer: Heat 1 tablespoon of oil in a pan over medium heat. Add the paneer cubes and lightly fry them until light golden on all sides. Take them out and put them aside. This golden crust adds a lovely texture.
I personally love the paneer cubes to be moderately fried until they attain a golden brown color but many prefer the paneer to be lightly fried or not fried at all, especially in palak paneer preparation. That is a matter of personal preference.
But make sure you do not fry them too much otherwise the spices and flavors will find it hard to penetrate deep inside of them.
Make the Onion, Chili, Ginger, and Garlic Mixture: In another pan, add the second tablespoon of oil. Add 1 tsp cumin seeds and let them splutter. Add the chopped onions and sauté until golden brown.
Add the minced garlic, grated ginger, and chopped green chilies. Sauté for another minute. This is where the kitchen starts to smell wonderful.
Add the Tomatoes: Add your de-seeded chopped tomatoes next, cooking them down till they’re soft and meld into a mushy mix. This creates a rich, tangy foundation. Add in salt as per your taste (around 1/2 tsp).
Blend the Ingredients and add the cashews: Transfer the cooked onion-tomato mixture to a blender along with the blanched spinach. Add about half a cup of cashew nuts for a creamy texture and to reduce the all-over bitter taste of the spinach.
Blend until smooth to form a vibrant green puree. Aim for a smooth, vibrant green puree. This is the heart of our dish.
Add in the spices: Pour this green magic back into the pan. Add the coriander powder, turmeric powder, garam masala, and salt to taste. Cook the mixture for 5-7 minutes, stirring occasionally, and watch as the colors deepen.
Add the Paneer: Gently add the fried paneer cubes to the spinach mixture. Stir well to coat the paneer evenly with the palak gravy, letting it soak up all those flavors.
Simmer and Serve: Let the Palak Paneer simmer for another 2-3 minutes to allow the flavors to meld together. This is where the magic happens, and all the flavors become friends.
Garnish and Serve: Sprinkle with fresh cilantro leaves. It adds a pop of color and freshness right before you serve. You can use a drizzle of cream as well along with chopped lemon pieces to give it a colorful look.
