As experienced chefs have explained, with quotes from the St. Petersburg television channel referencing the original source, this hack is not intended for mixing egg whites and yolks; that won't happen. The practical benefit lies elsewhere.
Such actions, the specialists noted, will significantly simplify the cooking process. If you shake the egg well before boiling, you won’t encounter issues when removing the shell afterward. It can be peeled off effortlessly without damaging the egg white. Therefore, it is indeed worth shaking the eggs thoroughly before placing them in boiling water.
Cooks also reminded us that it’s essential to add a spoonful of salt to the water to prevent the eggshell from cracking during heating, and after boiling, the eggs should be cooled in cold water.
