Chocolate Espresso Buttercream

Chocolate Espresso Buttercream
adapted from Professional Baking by Wayne Gisslen

3 ounces egg yolks [4-5 large egg yolks]
8 ounces water
2 ounces sugar
10 ounces unsalted butter
3 ounces semi-sweet chocolate
3-4 tablespoons brewed strong coffee/espresso
3/4 teaspoon vanilla extract

Place egg yolks in mixing bowl and beat on high until the yolks are light yellow in color and thick. This will take a good long while to happen - like 10 minutes. When I say thick, I mean thick! The number one way that I've screwed this up this recipe in the past is by not getting this step right.

Meanwhile, in a small saucepan combine the sugar and the water. Bring to to a boil, constantly whisking so that sugar does not burn. It is best to bring the mixture to a boil slowly so that all of the sugar crystals melt, otherwise you risk having gritty buttercream. Have a candy thermometer close at hand to measure temperature. Once the temperature reaches 240ยบ remove from the heat and pour into a glass Pyrex measuring cup. Very slowly pour the syrup into the egg yolks (I generally have a stream going down the side of the bowl to avoid hitting the whisk attachment). Continue to whisk on high until all the syrup is added and the mixture is completely cool. Again, getting this to cool takes a good bit of time. Go check your email or call your grandma and come back in 10 minutes.

A little at a time, beat in the butter. Be careful not to add the butter to quickly, otherwise the mixture won't absorb it.

Finally, melt the chocolate in a medium bowl and let cool slightly before adding the vanilla extract and the coffee. Let cool completely before mixing in one cup of the prepared buttercream. Thoroughly blend. Add remaining buttercream.

Eat up!
