In a mixing bowl, whisk together the yoghurt, gram flour, turmeric, salt and water, until smooth and lump free
Heat the oil in your cooking pot over medium heat and temper the fenugreek seeds, when they turn dark brown, add the onions, ginger and chilis. Stir to cook well
Once the onions turn translucent (do not let them brown), pour in the yoghurt mixture, over low heat
Cook while stirring this mixture continually until the flour cooks and the mix thickens - this should take about 7-10 minutes. Check for salt and adjust, if needed
Next add the spinach, mix well and simmer over medium heat, until the leaves cook completely (5-7 minutes). Turn the heat off when done. You can serve the kadhi at this point as well
For the tempering, heat the oil or ghee in a small frying pan, add the dried chili and the chili powder, cook for a minutes and pour it over the cooked palak kadhi
Stir this tempering in well and serve the palak kadhi or spinach in yoghurt sauce with steaming hot rice/pulao/khichdi. Enjoy!
