Instructions Combine the strawberries, sugar and water in a medium saucepan. Bring to a boil over medium-high heat and cook, stirring occasionally, until the strawberries break down, about 5 minutes. Remove from the heat and pour the mixture into a blender. Puree until smooth. Alternatively, you can strain the mixture through a fine mesh strainer, pushing the juices out of the strawberries. Pour the mixture into a small juice jug and add the tequila (or lemon-lime soda), cointreau (or orange juice) and fresh lime juice. Cover and refrigerate until cold or until ready to use. Combine the blueberries, sugar and water in a medium saucepan. Bring to a boil over medium-high heat and cook, stirring occasionally, until the blueberries soften, about 5 minutes. Remove from the heat and pour the mixture into a blender. Puree until smooth. Alternatively, you can strain the mixture through a fine mesh strainer, pushing the juices out of the blueberries. Pour the mixture into a small juice jug and add the tequila (or lemon-lime soda), cointreau (or orange juice) and fresh lime juice. Cover and refrigerate until cold or until ready to use. To make the floats layer 1-2 tablespoons of strawberry margarita with a few fresh berries, 1 scoop of ice cream and 1-2 tablespoons blueberry margarita until your glass is almost full (but leave a little room at the top). Pour the soda water over top until it reaches the lip of the glass. ENJOY!
