Abstract: The present invention relates to a method of preparing roasted sunflower shells containing seeds having a generally uniform coating of a flavoring agent thereon, which comprises subjecting raw sunflower shells to an elevated temperature, roasting the raw sunflower shells, quenching and coating the roasted sunflower shells after the seeds in the shells have been roasted to a desired degree, with a liquid flavor containing coating solution having a temperature below the roasting temperature. The quenching is carried out by spraying a finely divided liquid flavor containing coating solution onto the roasted sunflower shells while the roasted sunflower shells are at or near a roasting temperature, and while the sunflower shells are being agitated, and thereafter cooling the resulting coated sunflower shells to a temperature below at which the quenching step has been carried out.
