Add the ice cubes and Don Julio tequila (one ounce) in each glass.
Then add the sriracha sauce to the tomato juice and stir.
This cocktail is prepared in layers, so start with the first layer by pouring a little of the tomato juice, then add the grapefruit or grapefruit juice and, finally, the orange juice.
Garnish with a slice of pink grapefruit and a slice of natural orange.
Drink this vampire cocktail slowly and enjoy while you drip with fresh Mexican sauce and corn chips before the strong meal.
