  8. Put the eggs in the sauce bag and close tightly. The eggs should be submerged in the marinade. Let them marinate for overnight to up to 3-4 days in the refrigerator.

To Store

  1. Keep the eggs in the refrigerator all the time. Enjoy the eggs within 4 days if your eggs are soft-boiled. If your eggs are hard-boiled, you can keep in the refrigerator for up to a week. For safety, I recommend discarding the marinade and making a new batch if you want to make more.
