1. Separate the egg white and the yolk, add two drops of white vinegar to the white vinegar. Whisk the egg whites, adding sugar three times during the period.
2. You can lift the three or four corners of the egg whites. Since there are no pictures of the egg whites, you can take a look at the images found on the Internet.
3. Mix the milk powder and cornstarch through a sieve, add to the whipped egg whites and mix well. Remember to stir gently. Add the mixed protein liquid to the piping bag for later use.
4. Preheat the oven for 10 minutes, spread greased paper on the baking tray, squeeze the protein liquid on the greased paper, and then put it into the oven. 120 degrees for 30 minutes, you can set the time according to your own oven! It's not beautiful due to tight time, everyone, please forgive me! The oven stops working and wait for a while before taking out the melting beans! Remember that the oven must be preheated!
5. Finished product.
