Servings: 4 cups

Ingredients

  • 350 grams caster sugar
  • 170 grams egg whites around 5 eggs
  • 500 grams unsalted butter cubed, at room temperature/18℃
  • 1 tablespoon vanilla extract
  • 125 grams dark chocolate melted and cooled to 34℃

Instructions

  • bring a small amount of water in a small saucepan to a simmer, to create a double boiler
  • place the caster sugar and egg whites in the bowl of a stand mixer
  • put the mixer bowl on top of the saucepan of simmering water and whisk until the sugar has dissolved (if using a thermometer, it will be around 63-65°C). This will take 1-2 minutes
  • transfer the bowl to a stand mixer, then using the whisk attachment, whisk on medium-high until stiff peaks form (3-5 minutes) and meringue temperature comes down to 35℃
  • gradually add the butter cubes, mixing well between each addition
  • continue to whisk on high for around 5 minutes. The mixture will look curdled and pretty awful and you'll think you need to throw it out, but keep going - it will eventually become silky and smooth
  • Add vanilla extract and chocolate, then mix on low using the paddle attachment, for 3 minutes. Mixture will now be ready to use.

Notes

Thermomix method:
  • I use my Thermomix to heat the egg whites and sugar only, then whisk the meringue in my stand mixer.
  • To heat the egg whites and sugar, place into Thermomix bowl and set to 3mins/75℃/speed 2
  • Now add mixture to the bowl of your stand mixer and continue with whisking the meringue to 35
