A man in a blue shirt and green hat is preparing food at an outdoor stand. He uses a brush to apply a dark substance from a glass jar onto small, rectangular cakes. There is a tray full of the cakes next to the jar. He then places the cakes onto a black metal mold over what seems to be a cooking device. The stand is located next to a concrete wall with graffiti.
