For best results, ensure your egg whites are at room temperature. This will help them whip up to a greater volume. Be patient during the beating process; stiff peaks are essential for a stable frosting. If you don't have a double boiler, you can create one by placing a heatproof bowl over a saucepan of simmering water. Feel free to adjust the amount of coffee to suit your taste preferences. A bit of instant espresso powder can also be added for a bolder coffee flavor. This frosting is best used immediately but can be stored in the refrigerator for up to 24 hours. Re-whip before using.
