Christmas Cocktail

Combine sugar and water in a saucepan over medium heat, stirring until sugar dissolves completely.

Remove the saucepan from heat and let the syrup cool to room temperature, about 10-15 minutes.

Pour the cooled syrup into a large pitcher and add the unsweetened pineapple juice, lemon juice, and lime juice, stirring well to combine.

In a separate bowl, whisk the egg whites until foamy but not stiff, then gently fold them into the juice mixture.

Fill a large punch bowl or serving pitcher halfway with finely crushed ice.

Pour the cocktail mixture over the ice, stirring gently to chill thoroughly without breaking up the egg white foam.

Divide the cocktail among four chilled glasses, ensuring each serving includes crushed ice and some of the foamy mixture.

Garnish each glass with a single maraschino cherry and serve immediately.
