So like, who likes sour candy, and which is your favorite?
Mine would probably have to be Toxic Waste. It's similar to Warheads, but it's more sour (most of the time) and has a core that hits you surprisingly with another sour shock.

The only things I don't like about it are that it's hard to find, and it melts WAY too easily. And trust me, when it melts, the sour goes away and it tastes like shit. LITERAL shit. It's best to keep the container in the fridge when you are not eating it. But damn, it's sour as fuck and tastes awesome. If you have not tried it yet, order some!
