  • 12 fresh quail egg
  • 33 fluid ounces of water
  • 25 grams of leaf black tea
  • 50 grams of rock salt
  • 40 gr food grade sodium hydroxide
  • 150 gr beeswax


  1. First, to prepare the tea mixture, bring the water to a boil in a large saucepan. Add black tea and salt. Stir everything until the salt dissolves properly.
  2. Allow the tea mixture to cool completely to room temperature and then remove the leaves or sachets from the liquid.
  3. In a well-ventilated area, slowly pour the sodium hydroxide into the mixture. Stir the powder into the liquid with a stainless steel spoon until the powder is completely dissolved.
  4. Carefully add the eggs to the mixture one by one, being careful not to touch the sodium hydroxide liquid. Put the eggs into the solution with a colander or use a long tong.
  5. Cover the pot, ideally with a tight-fitting lid, and then label it with the date and contents. Store the container with the egg and liquid mixture in a cool, dark place for about 12 days.
  6. Using your protective gloves, open the pan and remove the eggs. Wash the eggs with brine and let them dry for an hour.
  7. Put the eggs in a plastic freezer bag or bag. Then put it in a pot with a lid. Restore it for about 24–30 days in a cool, dark place. We recommend storing it for twenty-four days when the weather is hot and thirty days when it is cool.
  8. After fermentation, remove the eggs from the pan using a slotted spoon or tongs and prepare the wax for the curing process.
  9. Melt the beeswax in a bain-marie. Be careful that the wax does not burn and that water does not enter.
  10. While the wax is melting, rinse the eggs very well under cold water and then lay them on a clean paper towel. Make sure they are completely dry.
  11. Once the wax is completely melted, wear food-safe gloves and dip the eggs into the wax. Dip the top halves of the eggs in the wax before placing them in the egg cup to allow the wax to solidify. Brush at least three coats of hot wax on top of each egg to create a thick layer.
  12. After the top of each egg is covered with a layer of wax, dip the bottom in the same way. Apply the same number (three coats) of wax as on the top.
  13. After the dunking process is complete, check that the wax is completely solid.
  14. After coating all the eggs with beeswax, place them in a container and store them in a cool, dry place for a few more weeks.
  15. Slice in half. Serve them with sesame oil, pickled ginger or sichuan sauce.

  • You can use any egg for this recipe. But duck eggs are traditional.
  • You can use tea bags instead of black tea leaves. In that case, you’d need around ten.
  • When making these black eggs, you should be careful around the sodium hydroxide solution. The effects of the liquid against bare skin are comparable to the effects of the kind of heat a stovetop generates. Therefore, make sure to be careful and use safety precautions if needed.
  • Put the eggs in the sodium hydroxide liquid with a slotted spoon or a long pair of tongs.
