Composite particles are provided that impart unique, entertaining optical and/or organoleptic effects in food products when exposed to an aqueous environment. In one embodiment, the composite particles have a least two layers which, when exposed to an aqueous environment, provide at least two sequential changes in the food product. Such changes can include changes in color or other visual appearance characteristics, flavor, and the like, as well as combinations thereof. In another embodiment, the composite particles are included in a powdered beverage mix wherein the powdered beverage mix itself provide the initial sequential change followed, by an appropriate delay, the second sequential change; further sequential changes can be provided, if desired, by providing additional layers with the appropriate optical and/or organoleptic ingredients therein.
