The sweet juice of the Ugli fruit tastes similar to a tangerine. With the addition of the other citrus fruits, the combination of flavors was just the zing I was hoping for. I have to say this margarita recipe is by far my favorite. And after doing some research, I found that Ugli fruit is an excellent source of vitamin C and fiber and contain fewer than 40 calories, about the same as a grapefruit.
Combine the sugar and water and heat just long enough for the sugar to melt. Remove from the heat as soon as the sugar has dissolved.
Refrigerate the simple syrup and allow to cool completely before adding to the other ingredients.
In a pitcher combine simple syrup with the lime, lemon, orange, and Ugli juices and zest and refrigerate until flavors meld, 4 to 24 hours.
Add tequila and orange liqueur and stir.
Salt rims of glasses by rubbing rim with lime slice and dipping the rim into some margarita or kosher coarse salt.
Fill glasses with crushed ice and fill with the Ugli margarita mix.
if you really wanna go the skinny route eliminate the addition of the simple syrup and the orange-flavored liqueur. Most margarita mixes are loaded with sugar—not to mention a long list of other ingredients you’ve probably never heard of.
