Start with your chicken pieces. You want to make sure they are clean and pat them dry with a paper towel. Season them generously with salt and pepper. This seasoning will become the base for flavor.

In a large, heavy skillet or Dutch oven, heat the pork fat or butter over medium-high heat. Add the chicken, skin-side down, and cook until the skin is crispy and golden, about 5-7 minutes. Flip the pieces and cook on the other side for another 5 minutes. Remove the chicken and set it aside.

In the same pot, add the minced onions. Cook until they turn translucent and begin to brown, about 5-6 minutes. The aim here is to develop sweetness by caramelizing them nicely; don’t rush this step.

Stir in the minced garlic, stirring for about 30 seconds until fragrant, then add the sweet and smoked paprika. Cook for another minute to toast the spices, ensuring you don’t burn them.

Add the chopped tomatoes and chicken stock to the pot. Scrape the bottom of the pan to release any flavorful bits stuck to it. This is where the magic happens as the flavors meld together.

Bring the sauce to a simmer and then add the chicken back to the pot. Toss in the bay leaf. Cover and let simmer for about 30-40 minutes, or until the chicken is cooked through and tender.

In a small bowl, blend the flour with a little water to create a slurry. Stir this into the pot and cook for a couple more minutes. It will thicken the sauce slightly.

Lower your heat and remove the pot from the stove for a moment to prevent the sour cream from curdling. Gradually mix in the sour cream and heavy cream until combined.

Taste and adjust the seasoning with additional salt and pepper. Serve hot, garnished with diced Hungarian sweet peppers if desired.
