Proper storage conditions, such as keeping the container in a cool, dark place, help maintain egg quality and prevent spoilage.

Here are some general tips to keep in mind:

Label and Date: Always label the container with the date you started waterglassing the eggs, so you know how long they have been stored.

Storage: Keep the container in a cool, dark place, ideally at temperatures between 50°F and 70°F (10°C and 21°C).

Use Within Six Months: While waterglassed eggs can last up to a year, using them within six months is advisable for the best quality.

By following these steps, you will be able to extend their usability well beyond the typical shelf life of fresh eggs.

How to Use Preserved Eggs

How to Use Preserved Eggs

Waterglassed eggs can change texture over time due to the pickling lime (calcium hydroxide). The egg whites can become more watery and less firm compared to fresh eggs, and the yolks may become more gelatinous or thicker, making them less runny and more difficult to separate from the whites. Lastly, the eggshells might become more fragile due to prolonged exposure to the alkaline environment of the lime solution.

However, the change in texture doesn’t effect their taste. They retain their freshness and quality and can be used just like fresh eggs in cooking and baking.

To make sure they are safe to use, follow these steps:

  • Inspect the Eggs: Check each egg for cracks or any signs of spoilage. Discard any eggs that look or smell bad.
  • Rinse the Eggs: Before using, rinse each egg thoroughly under cold running water to remove any lime residue.
  • Crack Open Carefully: Because the shells might be more fragile, crack the eggs gently. You might notice a change in texture, particularly with the egg whites being more watery and the yolks potentially thicker.

If it looks and smells okay, it will be safe to use. Plus, we really like the idea of having a supply of preserved eggs on hand, especially during times when fresh eggs are not readily available or there’s a shortage in the market.

Water Glass Eggs Tips for Best Results
