These look very pretty. They make good picnic food, too. If I’m taking them on a picnic I usually make a little fresh marinade (don’t use the marinade in which the chicken has already been steeping; you must make fresh stuff) and brush the chicken skewers with it before packing them. It helps keep them moist. Don’t forget that wooden skewers need to be soaked in water in advance for about 30 minutes; this stops them burning on the griddle.
