Special Equipment: 6 small cups, about 3 oz each, (recommended: Dixie), 6 popsicle sticks

Combine sugar, lime juice, water, lemon juice and orange juice in a small saucepan over medium heat. Cook, stirring, until sugar dissolves. Remove from heat and allow to cool. Once cool transfer to a blender with tequila, orange liqueur, and lime wedge and process until smooth. Pour into the cups and cover the top of each cup with foil. Make a slit and place the popsicle stick in center of cup (down through foil, which will hold it in place). Freeze until hard, preferably overnight.

Remove from freezer. Carefully tear the cups from around the popsicles. Garnish with kosher salt and serve immediately.

Note: Since the tequila makes these popsicles on the soft side, they must be eaten immediately.  If you want to sit them out for several minutes, set them on ice sprinkled with a little coarse salt.  And go ahead and sprinkle them with a little too.  This will give the  popsicles a few extra minutes of cold.
