Over on Idea Offer, a request was put out for the best ideas for cocktails that have ice cream as an ingredient.  And the winning idea came from Navakanth Kanapala for his Strawberry Margarita Fizz.  Here it is as described by Navakanth:

Strawberry Margarita Fizz

Sugar for coating rims of glasses
1-1/2 cups softened strawberry ice cream
1/2 cup chopped strawberries, plus whole strawberries for garnish
1 ounce tequila, or to taste
1/2 teaspoon fresh lime juice
1/3 cup chilled club soda
Garnish: lime slices

Rim edges of two highball glasses with sugar, and set aside.  Place ice cream, chopped strawberries, tequila, and lime juice in a blender.  Mix until all ingredients are combined and smooth.  Divide strawberry mixture between the two glasses, and top each with half of the club soda.  Stir gently to combine.  Garnish with limes and strawberries, if desired.

Makes me want to get some ice cream and umbrellas and head to the beach!
