Taco Bell isn't one to shy from giving out free salsa. The fast food chain's colorful assortment of Verde, Mild, Hot and Fire salsas have always available for customers to drench their DLTs with. Looks like they can soon add yet another color to their collection.

Earlier, we received a mysterious package in the mail. Upon opening it, we discovered a sleek black single packet of hot sauce. It was called Diablo.

Thanks, Taco Bell.

Diablo is set to make its debut May 5 and will be available for a limited time only.

We tried the new hot sauce and compared it to its current hottest packet, Fire. The taste is actually really good and it's noticeably spicier than Fire. However, it could definitely be spicier.

Sure, Taco Bell says you only need one packet to satiate your spicy sauce needs. Though a few more wouldn't hurt.
