This is done with a Vitamix VM0178 blender in the 40-oz. to-go cup. I still intend to scale it up to a pitcher for additional servings.
Two cubes of ice.
One cup of cold, filtered water.
Two tablespoons of sugar.
Two tablespoons of Santa Cruz organic lime juice.
1/8 tsp of xanthan gum
Pour all this stuff into the 40-oz. to-go cup. Screw in the teeth. Shake briefly. Place the cup on the Vitamix. Blend until all gredients are incorporated.
You can also throw in a few ounces of tequila just for fun.
