# Directions:
01 - Combine mayonnaise, sour cream, minced garlic, lime juice, lime zest, and optional hot sauce in a small bowl. Season with salt and pepper. Refrigerate until needed.
02 - In a large bowl, whisk together flour, cornstarch, baking powder, salt, garlic powder, paprika, and black pepper. Gradually add cold sparkling water, stirring until a smooth batter forms.
03 - Pour vegetable oil to a depth of about 1 inch in a deep skillet or Dutch oven. Heat over medium-high until reaching 350°F (175°C).
