Combine sugar and egg whites in mixer bowl, and set over a pan of simmering water. Whisk constantly until sugar is dissolved and mixture registers 140 degrees on an instant-read thermometer.
Transfer bowl to mixer; whisk on medium-high speed until whites are fluffy and cooled, about 10 minutes. Continue to whisk until stiff, glossy peaks form.
Reduce speed to medium-low; add butter by the tablespoon, whisking well after each addition. Whisk in vanilla.
Buttercream can be refrigerated in an airtight container up to 3 days or frozen up to 1 month. Bring to room temperature before using; beat on lowest speed until smooth, about 3 minutes.
would love to see how the roses are made
I love this icing. However, when I attemped to color the icing. . .i used Wilton gel paste colors, it didn't take. Not sure why? would the AmeriColor Gel work better? Whats the best way to tint or color this icing?
