Ever make Jell-O Jigglers? They stay semi-solid at room temperature, and they’re firm enough to cut into shapes. Why not make intense mini-shapes to use as fruit-flavored sweetener for tea? Put them on the end of flavored toothpicks if the “can’t touch any actual ingredient” issue is a problem. Make them so they dissolve in cold liquids, and you could turn water, bottled or otherwise, into a soft drink, low-cal flavored water, or even a sports drink.
