Homemade Century Eggs

First of all, century egg or thousand-year old eggs 皮蛋 as they are sometimes called are not one hundred years old. They are simply eggs that have been treated in a basic solution that dramatically transforms them into a striking accompaniment to jok or savory rice gruel. My first attempt at homemade century eggs was an epic failure, so victory this round was especially sweet.

  1. The ingredient list doesn’t include salt, but the instructions say to mix salt and other ingredients into the water to dissolve. How much salt??

  2. I love how joyous you are at finally being able to create these eggs. Congratulations Emmy! I love watching your videos. You have the best way of describing how different foods taste, I almost feel like I can taste them. ❤️

  3. left the 16 grams of kosher salt off the recipe….. but it’s in the video. Watch the vid!

  4. 5 stars
    The video and your success had me jumping for joy! Wonderful for the recipe! How long would the diffusion take for the chicken and duck eggs respectively? Regarding the pu-erh tea, can any black tea work?
    Stay safe and fantastic Emmy!

  5. YAY!!! I’m so glad you loved it too. 😀 I would imagine black tea would work, but as far as diffusion time, I think that would be a matter of trial and error.

  6. So sad. Have of my eggs didn’t survive the soak. 🙁 Onward with the other half into the dark cabinet! Wish me luck!

  7. I’ve been curious about eating/making these for a long time. I just ordered the ingredients but have to wait until I’m back from vacation to make them. Can’t wait!

  8. Hi Emmy!
    I don’t have access to quail eggs, can i use chicken eggs?
    Because chicken eggs are larger than quail eggs, how long should i soak and rest store the eggs?
    Thank youu!

  9. I just made these and they turned out great! I haven’t seen any pineflowers yet but otherwise they look perfect. The flavor is much more mild than I anticipated. My big question is how to store my century quail eggs now that I have them. I have a feeling they won’t last long!
