Candy Addict has reviews of some wacky new flavors of candy:
--Strawberry Milkshake Whoppers, and
--Chocolate Pop Rocks
I get the sense that both will have that sicky-sweet fake chocolate or strawberry flavor, and that the resulting candy would be just disguesting, with a horrid aftertaste.
A review of something that does sound edible: Milkshake Kit-Kats, which reminds me of the green-tea and other flavored Kit-Kats we found in Japan.
