Frequently Asked Questions

What's the difference between expiration and best quality dates?

β–Ό

Salted duck eggs have a long shelf life due to their preservation method. The expiration date on commercially produced salted duck eggs usually indicates when the quality may start to deteriorate. While the eggs may still be safe to eat past this date, the taste and texture may not be optimal.

Over time, the yolk may harden and the flavor can become more intense, which some people may prefer.
