The key to the quick fixings and quick clean-up for me is the use of an immersion blender. You can certainly use a standard blender, but the immersion blender and the cup that comes with it is really all you need. It makes it super fast to make (less than 15 seconds of blending) and super fast clean up -- just drop the blade end and the blender cup in soapy dishwater.
One Minute Frozen Margarita (Optional Strawberry)
2 ounces Silver Tequila
1.5 ounces triple sec or orange liqueur
2 ounces Rose's lime juice
Fill the immersion blender cup (or standard blender) with 1 cup crushed ice. Add alcohol and lime juice. Using the immersion blender (or standard blender) blend for about 15 seconds until ice is completely blended (may take longer in a standard blender).
For strawberry version, reduce lime juice to1/2 ounce and add 5 whole large strawberries (washed and leaves removed) and 2 T. simple syrup.
Pour into margarita glass. If salt or sugar (for strawberry variety) is desired, rub edge of glass with a juicy lime slice, and dip glass upside down in a dish of coarse salt or sugar.
Simple Syrup: 1cup sugar, 1 cup water: In a small saucepan, bring sugar and water to a boil; simmer until the sugar is dissolved, a couple minutes. Remove from the heat and let cool completely. Store int he fridge for up to a month and use in other cold beverages like iced tea.
