First of all, clean and wash all the greens thoroughly.
Chop them and add in the pressure cooker, I added in the instant pot.
Add chopped garlic, chopped onion, tomato, and green chilies.
To this add chopped radish, and chopped ginger.
Add 1 cup water and set the button PRESSURE COOK. Set the valve in sealing mode. Pressure cook for 2 minutes. If you are using a stovetop pressure cooker then 4-5 whistle is enough to cook.
Let the pressure release on its own. Open the pressure cooker/instant pot. Stir nicely.
puree it with the help of immersion blender. NOTE if you do not have an immersion blender then let the mixture cool down and then use mixer/grinder.
I like coarse texture if you like smooth consistency then puree it till smooth texture.
Add red chili powder, and salt as per taste. Mix well.
Set the SAUTE mode and set the heat low.
Mix maize flour (Makki ka atta) in 1/4 cup water to make a paste. Add this paste in the saag and mix nicely. There should not be any lump. Saag will start thickening.
Cook for 1-2 minutes. Saag splutters a lot at this time, so careful while stirring it.
Saag will thicken after 2 minutes. CANCEL SAUTE mode and switch off the instant pot. Take out the insert from the instant pot.
