Strawberries and Champagne go together like kisses at midnight. A shot of tequila makes this a powerhouse cocktail that makes it a great option for both sweet-style drinkers and those that like the strong stuff.
Wash, stem, quarter and freeze strawberries for at least 1 hour (can be done the day ahead). Run a wedge of lime around the rim of your Champagne flute and dip in a plate of sugar to coat rim. Place a frozen strawberry at the bottom of the flute. Open Champagne and pour glass approximately ⅔ of the way full. In a shaker filled with ice, combine tequila, limeade, and strawberry liqueur. Shake. Add a squeeze of fresh lime if desired. Top glass with the cocktail and serve immediately.
