Baja Blast is a variety of Mountain Dew soda that’s made exclusively for Taco Bell restaurants. This lime-flavored drink is known for its unique and distinctive aquamarine color. Although this is a very popular drink, you can't actually buy it in bottles or cans in a grocery or convenience store. So if you have a hankering for Mountain Dew Baja Blast but cannot get to the restaurant, one option is to make a version yourself by blending Mountain Dew and Gatorade.
