Empty the tea bags and add the loose tea to the bowl, then set the bowl over the saucepan of simmering water and whisk until the mixture is hot and the sugar dissolves, about 2 minutes.

Transfer the bowl to the stand mixer and beat with the whisk attachment on medium-high speed until the mixture holds stiff peaks, about 5 minutes.
