Persian Chicken and Walnut Stew (Khoresh-e Fesenjan)

Heat 1 tablespoon of olive oil in a large pot or Dutch oven over medium-high heat. Add the chicken pieces and sear until lightly browned on all sides, about 5-7 minutes. Remove the chicken from the pot and set aside.

Reduce heat to medium. Add the chopped onion to the pot and cook until softened and translucent, about 5-7 minutes, stirring occasionally.

Stir in the finely ground walnuts. Cook for 5 minutes, stirring constantly to prevent burning, until the walnuts are fragrant and slightly darker.

Pour in the pomegranate molasses and 1 cup of water. Bring the mixture to a gentle simmer, then return the seared chicken to the pot.

Add salt, black pepper, and the optional sugar. Stir well to combine.

Reduce the heat to low, cover the pot, and simmer for at least 75 minutes, or until the chicken is very tender and the sauce has thickened to a rich consistency. Stir occasionally to prevent sticking.

Taste and adjust seasoning if necessary, adding more sugar for sweetness or pomegranate molasses for tanginess, if desired. Serve hot.
