Whip the egg whites with a drop of lemon juice. First, whisk at low speed. Then gradually increase the speed. At high speed, add powdered sugar one teaspoon at a time, adding every 20-30 seconds. After adding the powdered sugar, whisk the cream for another 5 minutes.

Divide the whipped egg whites into several parts in a clean bowl, adding the desired color dye to each.

Spoon or pipe the meringue onto a baking tray. Bake at 70℃ for 2-3 hours. Leave in the oven until cool.
