Yesterday, I explained how to make the perfect macaron shells, so this recipe is for the filling of the macarons. You can also use French buttercream with other desserts too!
To get started, go ahead and measure out all of your ingredients. Then in a stand mixer, put in your egg yolks and start whisking on medium-high. In the meantime, you will start cooking your sugar syrup. This is the same process you use for the macaron shells sugar syrup. Place the water and sugar together in a sauce pan, and with your finger or a spoon, give it a quick whirl to make sure there is no sugar stuck to the bottom of the pan. Heat the sugar and water over high heat. With a thermometer, check the temperature. When the syrup reaches 244 degrees F (118 degrees Celsius), remove it from heat.
Your egg yolks should have lightened up a lot by now. Turn the mixer speed on low, and slowly pour your sugar syrup down the side of the mixer bowl. The hot sugar syrup cooks the egg yolks. Turn the mixer back up on high speed, and mix for a few minutes to cool down and become room temperature. When done, your egg yolks should form stiff peaks. At this point, your egg yolks should be really light in color.
Continue to mix on low-medium speed, and add your butter in bits at a time until combined. Make sure to stop and scrape the bottom and sides of the mixing bowl every so often so it all gets mixed in evenly. Then you can add in your vanilla, or whatever extract or flavor you would like the filling to be. The buttercream should be almost white when it is done. The last step, is to add in whatever food coloring you would like. I like to use Wilton gel food colors, you can buy them here.
Then using a round nozzle, fill up your piping bag, and you are ready to go! Get the nozzle and piping bag kit here.
