Notes
Virgin Margaritas:
This recipe can easily be modified to be non-alcoholic, by leaving out the tequila and triple sec. Use seltzer water to replace the alcohol and add more as needed blending until the thickness is to your preference.
Ideas for garnishing:
Dampen rim of glass with lime juice or water and dip in salt for a classic margarita. You can do the same using granulated sugar. Decorate with slices of lime or fresh strawberries attached to the rim of the glass.
16 ounces of frozen strawberries can be used in place of fresh strawberries. Thin with water as needed.
Adjust amount of liquor using more, or less, to your taste.
