The Lucas Gusano is a spicy candy from a Mexican snack company called Lucas. Packaged in a plastic bottle that squeezes like an accordion, the Lucas Gusano drops little squirts of exotic goodness on your tongue. You might even mistaken it for hot sauce at first glance -- the flaming red cap and viscous red liquid is not what you'd normally see in the candy section at convenience stores.
There are two flavors of the Lucas Gusano: the chamoy, which is a traditional Mexican seasoning made of pickled fruit and tamarindo, a type of chili. While the chamoy is more salty, the tamarindo is intensely spicy. Traditional spices and flavors are often infused into snacks and candy in Mexico.
