1 cup tequila
1/4 cup Triple Sec
1/3 cup cranberry juice
1/4 cup cranberry juice
1/4 cup (or more cranberry sauce)
handful frozen (or fresh) cranberries)
Fill half a blender (or so) with ice; add rest of ingredients and puree until ice is crushed. If your cranberry sauce is not too sweet, you may want to add a bit of sugar.
