Line an 8-inch square pan with wax paper, ensuring the paper is smooth and extends over the edges for easy removal.

Combine the white chocolate chips and sweetened condensed milk in a medium saucepan. Heat over low heat, stirring constantly, until the chocolate is completely melted and the mixture is well combined.

Stir in the champagne and mix thoroughly. The mixture will slightly fizz; continue to stir until it returns to a smooth consistency.

Add the strawberry puree and a pinch of salt to the chocolate mixture. Stir until the puree is fully incorporated.

For a more vibrant color, stir in a few drops of red food coloring until the desired hue is achieved.

Pour the fudge mixture into the prepared pan, smoothing the top with a spatula.

Refrigerate the fudge for at least 2 hours or until it is firm.

Once set, use the wax paper to lift the fudge out of the pan. Place on a cutting board and cut into squares.

Serve chilled and enjoy the harmonious blend of strawberries and champagne in this decadent fudge.
