What attachment should I use to beat the meringue?
Use the whisk attachment on your stand mixer for the initial meringue phase.
When should I switch to the paddle attachment?

Beat the mixture on high speed until it cools; the peaks should stand upright when the whisk is lifted.
Why do I need to wipe the bottom of the bowl after heating?
Wiping the bottom dry prevents any condensation or water from dripping into your stand mixer or the frosting.
Can I use salted butter instead of unsalted?

What should the speed of the mixer be when adding butter?

A single pinch of regular table salt is used to enhance the flavor.
Is this buttercream very sweet?
No, it is described as perfectly balanced in sweetness, making it less sugary than traditional American buttercream.
