Dip the top of a lowball glass in a bowl of water, then into a plate of salt, moving it side to side until the rim is evenly coated.
Next, add crushed ice to the glass.
Pour in the Tequila, Fresca soda, and a squeeze of lime.
Give your skinny margarita a quick stir, garnish the glass with a slice of lime, and enjoy!
Notes
Another way to salt the glass rim is to run a wedge of lime around it and only roll half of the rim in salt. You can also pour a very small amount of salt into the plate, so you'll only get a thin lining around the rim when you dip the glass in the plate.
Play around with your rim salt! Combine salt with chili powder or chamoy to take your skinny margarita's flavor to the next level.
The best skinny margarita recipe uses fresh-squeezed lime juice, not bottled lime juice. Make sure the lime is at room temperature, roll it back and forth on a flat surface with gentle pressure, and cut it lengthwise. You can also use a handheld citrus juicer!
For a frozen margarita, blend the margarita ingredients, some ice cubes, and frozen fruits in a blender. This three-ingredient margarita will be delicious with frozen blueberries, strawberries, and mangoes.
