A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The flavor source includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a gelling agent that imparts sufficient structural framework for rigidity to the flavor source. The material is mixed, extruded through a die, and cut into the shape of a one-piece flavor source. The flavor source is loaded into a chamber for inclusion in a smoking article as a flavor generator.
