Notes
As mentioned in the post, you can make this kurma only with turnips or with a combination of vegetables.
Adjust the spices and salt according to your preference.
Instead of cashews, you can use roasted gram or pottukadalai.
Instant Pot Version: If using IP, saute the onion and the ground paste in saute mode and add the veggies and water. Then pressure cook at high-pressure manual mode for 4 to 5 minutes and let the pressure release naturally.
