My measurements are by using the empty can

• 1 (6 oz) can frozen limeade concentrate
• 1 can tequila
• 2/3 can triple sec
• 2/3 can amaretto
• 1/2 can orange juice
• 1 packet or 1 tsp Splenda

1.  Dip rims of glasses in amaretto, then into sugar; set aside.2.  Combine all ingredients into the pitcher of the blender.3.  Add ice by small handfuls while blender is running on med-high and continue adding until you reach your desired consistency.  (Adding the ice in small batches makes for a smooth frozen margarita!) Most of all… Enjoy! http://www.opensourcefood.com/people/janedeere/recipes/italian-margarita
