Meringue

I made meringue for the first time)))) The creative inspirer, Inna Kondrashova!!!!
4 cold egg whites
1 cup of sugar
Whip the egg whites into a fluffy foam, while continuing to whip, gradually add the sugar, whip until stiff peaks form (so that the mixture retains its shape), place on parchment paper, no need to grease it, and most importantly, the meringue should be placed in a cold oven!! Place it in, turn it on, and heat to a temperature of 100-110 degrees Celsius for 1-1.5 hours, do not open the oven.
