Crisp on the outside and juicy in the middle, Iranian kotlets are made from mixing grated potatoes and onions with ground beef or lamb and spices, then forming them into patties before frying. Every Persian household has its own signature spice blend, or advieh, and it traditionally includes a variety of spices such as cumin, turmeric, cinnamon, cardamom, rose petals and cloves. Typically eaten for lunch or taken along on picnics, kotlets are great hot or at room temperature; they can be served right away with steamed basmati rice or saved for later, tucked into a sandwich with tomatoes, pickles and herbs.
