If spiced tea eggs are too tasteless, you can try the following methods:

1. Incision: You can cut several knives on the surface of the tea egg to make the fragrance in the egg easier to penetrate.

2. Add salt: Add some salt to the water where the tea eggs are boiled to make the tea eggs taste deeper.

3. Add more seasonings: After the tea eggs are cooked, add more seasonings, such as soy sauce, pepper, ginger slices, etc., to make them more flavorful.

4. Pickling: Marinate the tea eggs for several hours before boiling, so that the taste inside the eggs can penetrate better.

5. Longer cooking time: The time for cooking tea eggs can be extended, so that tea eggs have more time to absorb seasonings and taste deeper.
