How do I know if I’ve whisked my meringue mix enough?
It should have formed stiff, glossy peaks, and you could even turn the bowl upside down without it falling out. A metal whisk works best, as the metal creates more resistance, whipping the egg whites more effectively. Before you start, make sure your bowl is clean and free from grease, and don't get any egg yolk in the mix. Watch out useful video on how to make the best meringues!
