Earl Grey Swiss Meringue Buttercream

This Earl Grey Swiss Meringue Buttercream looks beautiful speckled with earl grey tea and has a light, slightly citrusy flavor.  In the above picture, I’ve paired this buttercream with Buttermilk Yellow Cake and Blueberry Preserves in my Blueberry Earl Grey Cupcakes.
 

Ingredients:

• 2 egg whites
• ½ cup sugar
• 2 sticks butter, room temperature, cut into pieces
• About ½ to 1 teaspoon loose leaf earl grey tea (amount should be adjusted to taste; some brands of earl grey tea have stronger flavor than others)

In a spice grinder or food processor (I use the Cuisinart 14-Cup Food Processor), grind or process the earl grey tea leaves until they become a fine powder.  I used a fine mesh sieve to make sure the tea leaves were fine enough so that when mixed into the buttercream, it will not lose its smooth, silky texture.  Set aside.  

Whisk together egg whites and sugar in a mixing bowl over simmering water until sugar has dissolved and egg whites are warm.  Using a stand mixer, beat the egg whites until meringue is a glossy white and can hold stiff peaks, about 3-5 minutes.  Add the Earl Grey tea powder and beat until evenly distributed.  

Scrape down the sides of the bowl and add the butter all at once.  Slowly increase the speed to high and beat until mixture is homogeneous, about 2 minutes.
