Season the chicken with salt. Set aside.
In a dutch oven add the ¼ cup lard and heat it up. Once it's melted, add the 2 diced onions. Saute the onion until translucent.
Once the onion is translucent, add the 2 cloves of garlic and stir for another minute. Remove the dutch oven from the heat. Add the 2 tbsp sweet paprika and stir to coat the onions completely.
Add the 6 pieces of bone-in chicken and stir to coat the chicken in the paprika. Put the pot back on the heat.
Add the lid onto the pot for 5 minutes. Check the chicken. If it is releasing liquid (enough to come up the sides of the chicken), you do not need to add more water. If the pot still looks dry, add about 1 cup of water into the dutch oven, or enough to cover the chicken about halfway.
Add the lid back onto the pot and let it cook for 20 minutes. Then open the lid, flip the chicken, put the lid back on and cook for another 30 minutes or until the chicken is cooked through and reaches 165 degrees Fahrenheit.
Use tongs to remove the chicken from the dutch oven and set aside.
Put the 6 tbsp sour cream in a small bowl and spoon in a few spoonfuls of the sauce from the pot. Mix it up in the bowl to make it smooth.
Add the sour cream mixture into the dutch oven and mix to combine. Then, use a food processor or immersion blender to blend the sauce until it is completely smooth.
If your sauce is very thin: Add 1 tbsp of flour into a small bowl with a few spoonfuls of sauce from the dutch oven. Mix until smooth, then pour into the pureed sauce, allowing it to cook for a few minutes over medium heat. This will thicken the sauce.
Add the chicken back into the sauce. Serve with noodles, dumplings, or mashed potatoes. Enjoy!
