Grand Marnier Buttercream Frosting          

Ingredients:
2 cups sugar
2/3 cup water
6 egg whites
1 pinch salt
1/4 teaspoon cream of tartar
1 1/4 lbs butter, softened
1 teaspoon vanilla
3 tablespoons Grand Marnier
 

Directions:
Combine sugar and water in saucepan and bring to a boil. Cover and let boil 3-5 minute until sugar dissolves, uncover and continue boiling until syrup reaches 238° on a candy thermometer (soft-ball stage).

Meanwhile, place egg whites in the bowl of a standing mixer fitted with the whisk attachment, and beat on low speed until foamy. Add cream of tartar and salt, and beat on medium-high speed until stiff but not dry; do not over beat.

When syrup reaches 240 degrees pour 1/4 cup of syrup into egg white mixture. With mixer running, add syrup to whites in a stream, beating on high speed until no longer steaming, about 3 minutes. Add rest of syrup slowly and beat for 8-12 min., or till cool, so butter will not melt.

In separate bowl cream butter. Add butter bit by bit, beating until spreadable, 3 to 5 minutes; beat in vanilla and Grand Marnier. If icing curdles, keep beating until smooth, may still be too warm. Use Immediately!
