My friends and I used to hang out at a tea house in Chinatown and we'd always order tea eggs. These are much more attractive with a crackle glaze and are a fun snack to serve when guests come over to visit.
Unpeeled eggs can be refrigerated in a covered container for up to 4 days.
Make the eggs in bulk and serve during Chinese New Year when guests come to visit.
If you are in a hurry (or just lazy), skip steps 1 and 2. The eggs won't be as pretty but they will be just as tasty.
