First Step In Making Italian Meringue Buttercream

Meanwhile, begin whipping your room temperature egg whites and a pinch of cream of tarter. You want both of these mixtures to be ready at the same time. If the syrup is late to the frosting game, just lower the speed of your mixer to keep the egg whites stiff.

Once your Syrup is ready, you will get your mixer turned to high then drizzle it slowly into the egg whites. Make sure you don’t pour it right onto the whisk attachment. Keep a steady stream going. Then just let it whisk for ten to twelve minutes, or until the heat of mixture goes down. Ensure that your frosting won’t melt your butter, so it is important that you let this cool down and whip long enough. Touch the bowl to check.
