Blueberry Swiss Meringue Buttercream

Swiss meringue buttercream uses the magic of egg whites, sugar and butter to create this lighter than air, pillowy frosting that is worth the effort. I added the juices from a quick blueberry compote and amplified the berry flavor with a bit of Chambord black raspberry liquor. I made cupcakes here, but if you make a layer cake you can fill the middle with a good thick layer of your favorite prepared lemon curd (I love Wilkins & Son's from Tiptree England). This is fast becoming my most requested birthday cake. Such a treat.

3 large egg whites at room temperature

3/4 cup granulated sugar

3 sticks unsalted butter at room temperature

1 tablespoon Chambord black raspberry liquor

1/2 teaspoon kosher salt

1/2 cup strained juices from blueberry compote (recipe to follow)

  • In the bowl of a stand mixer, combine the sugar and egg whites

  • Place the bowl over a saucepan of simmering water

  • Whisk constantly until the sugar is dissolved and the whites start to become white and frothy, about 5 minutes

  • In the stand mixer with the whisk attachment, whip the egg whites on high until stiff glossy peaks form, about 10-12 minutes

  • Add the butter about a tablespoon at a time, mixing well after each addition

  • Scrape down the sides of the bowl, and with the mixer running on low, add the blueberry juices, salt and Chambord and beat until well combined, about a minute

  • Frost the cupcakes or cake and drizzle the blueberry puree on top, decorate with basil and or nasturtiums if desired, they do add a nice flavor hit

Serve with 3 cups of fresh blueberries and or raspberries
