Colorful protein sugar

1. In a pot without water or oil, separate the egg whites and add white sugar. The eggs I used are of medium size, and two egg whites weigh about 85 grams. White sugar is ordinary white sugar, 90 grams. The sugar content can be adjusted according to the size of the eggs.

2. Place the bowl in warm water at around 50 degrees Celsius, heat it in a water bath, and stir until the sugar is completely melted. Be careful not to overheat the water temperature and avoid scalding the eggs.

3. According to your favorite color, use a toothpick to apply the pigment to the piping bag, and squeeze it out to create very casual colored stripes.

Preheat the oven to 100 degrees, place it at 90 degrees, turn on the hot air circulation for more than an hour. Bake until it doesn't stick to your hands, gently pick it up, that's good. Be careful not to raise the temperature, it will turn yellow if it's too high.

5. A crisp taste that melts in the mouth indicates success.

6. When it cools down, quickly pack it in a sealed container and avoid getting damp. It can be stored in a cool place for a week without any problem.
