Personally, I think it is best to use black tea to make tea eggs, because black tea is fragrant but not bitter, and its color is bright. The boiled eggs are rich in fragrance, uniform in color and excellent in appearance. First, black tea is rich and mellow, without bitterness, and the boiled tea eggs are rich in aroma and bright in color. Then black tea is not harmful to the stomach, because tea polyphenols, an important substance contained in tea, are astringent and have a certain stimulating effect on the stomach. Black tea is made by fermentation and baking. Under the action of oxidase, tea polyphenols are enzymatically oxidized, the content is reduced, and the irritation to the stomach is reduced.

However, if green tea is bitter, the boiled eggs will be astringent, and green tea is cold, which is not suitable for people with stomach problems, infirmity and pregnant women.
