Take 700 grams of chicken. Cut them in medium-sized pieces and wash them nicely with salt and vinegar. Also, make slits in the leg pieces. Keep them aside.
Now, pour 1 tbsp of olive oil in a kadai. When it is slightly hot, put in 2 pieces of cloves, 2 pieces of bay leaves, 15 pieces of black pepper corns, 2 pieces of green cardamom, 1 piece of black cardamom along with 12 cloves of garlic (peeled, roughly chopped). Stir and fry them over a medium flame for about 20 seconds or so. Then, add 1 piece of onion (medium size, finely sliced) and turn the flame to high. Cook till the onions turn soft and translucent.
Now, put in 2 pieces of finely chopped green chilies and cook for about 10 seconds.
Then, add the chicken pieces to it. Stir intermittently and cook it over a medium flame this time for about 6 to 7 minutes until the color of the chicken pieces changes.
Now, add cubical pieces of half a carrot and one potato with skin to it along with salt to taste and ¼ tsp turmeric powder. Mix everything very nicely and cook them for another 2 to 3 minutes over a medium flame. Then, add 2 pieces of tomatoes (each cut in half) along with 5 pieces of coriander stems to it and mix them well.
Now, pour in 1 liter of water to it and mix nicely. Cover the kadai, turn the flame to high and let it come to a boil.
While the chicken cooks, prepare a rice flour slurry with 1 tsp of rice flour and water as needed. Check the consistency. It should not be too thick.
Pour the rice flour to the chicken stew after 5 minutes of cooking and mix very nicely. Remove the skin from the tomato pieces using a pair of tongs. Cover and cook it for another 15 to 20 minutes, this time over a medium flame. (Pro tip: Do not cook the chicken over a high flame after adding rice flour slurry, or else the chicken will not be soft).
After 20 minutes, check the doneness of the potatoes using a knife.
Now, add 10 pieces of spinach leaves (chopped roughly) to it. Mix well, cover and cook for another 2 to 3 minutes.
Finally, add ½ tsp of crushed black pepper to it, mix well. Check the doneness of the chicken.
Your tasty and healthy homemade chicken stew is ready to enjoy. Transfer it into a serving bowl and serve hot as is or with bread toast.
