An improved method for imparting a flavor to a product, the method comprising adding to the product an organoleptically effective amount of a dicarbonyl or a mixture thereof, the improvement comprising substituting for the dicarbonyl, an organoleptically acceptable derivative thereof having the formula (I) or (II), wherein m=0, 1 or 2, n=1 or 2, R1 and R2 are, independently, linear or branched saturated C1-4 alkyl, with the proviso that both of R1 and R2 may not be methyl, and X is a counterion. Typically, R1 and R2 are methyl (with the above proviso), ethyl, propyl (e.g. n- or i-propyl) or butyl (e.g. n-, i- or t-butyl), or an organoleptically acceptable salt thereof, as well as compositions for carrying out the method and products and articles of manufacture comprising the additive.
