Ingredients

How to make it

  • Combine egg whites and salt in a large bowl.
  • Stir together brown sugar and water in a small heavy saucepan and bring to a boil over moderately high heat, washing down side of pan with a pastry brush dipped in water.
  • When sugar syrup reaches boil, start beating whites with an electric mixer at medium-high speed until frothy, then add lemon juice and beat at medium speed until whites just hold soft peaks.
  • (Do not beat again until sugar syrup is ready.)
  • Meanwhile, put candy thermometer into sugar syrup and continue boiling until syrup reaches 238–242°F.
  • Immediately remove from heat and pour into a heatproof 1-cup glass measure.
  • Slowly pour hot syrup in a thin stream down side of bowl into egg whites, beating constantly at high speed.
  • Beat meringue, scraping down bowl with a rubber spatula, until meringue is cool to the touch, about 6 minutes. (It’s important that meringue is properly cooled before proceeding.)
  • With mixer at medium speed, gradually add butter 1 piece at a time, beating well after each addition until incorporated.
  • (If meringue is too warm and buttercream looks soupy after some of butter is added, briefly chill bottom of bowl in a large bowl filled with ice water for a few seconds before continuing to beat in remaining butter.)
  • Continue beating until buttercream is smooth.
  • (Mixture may look curdled before all of butter is added, but will come back together before beating is finished.)
  • Add vanilla and beat 1 minute more.

    This sounds so luscious! I once made something similar and overcooked the sugar syrup. It turned into hard candy. I had to redo it and was more careful the second time. I remember it was the best frosting ever!
