Summer is about 1 day, spring and autumn is about 2 days, and winter is very long, but I suggest not brewing for a long time. Because the tea leaves in the tea eggs will react with the air after being soaked for a long time and produce some substances harmful to human health, it is not advisable to soak them for too long!

Tea contains biological acid-base components and acidic substances, which will penetrate into eggs after cooking and combine with iron in eggs; Combined, it will stimulate the stomach and affect the absorption and digestion of nutrients for a long time, which is not conducive to human health. So eat less.

Finally, soak the eggs in boiling water, but don't stick to raw water, otherwise there will be a lot of bacteria, and then the eggs will go bad.

If you want to know the formula and making method of tea eggs, you can read my answer a few days ago and write it down carefully for everyone to ensure that everyone can make delicious tea eggs!

This is the answer for you. I wonder if it will help you.
