1Separate egg whites from egg yolks. Use only the egg whites.
2Add egg whites and sugar to a large bowl and whisk together.
3Place the bowl over a pan of simmering water, ensuring the water doesn't touch the bowl. Whisk constantly until the sugar dissolves and the mixture is smooth.
4Whisk the warm mixture with a stand mixer on medium speed until stiff, glossy peaks form.
5Slowly incorporate room temperature butter into the meringue, mixing until smooth. If it looks like cottage cheese, keep mixing until smooth.
