Glassing Eggs
How to Preserve Eggs for Winter
As winter approaches and fresh eggs become less abundant, storing eggs is a valuable skill for anyone looking to maintain a steady supply. One traditional method that works beautifully is called "water glassing." Water glassing preserves fresh eggs for several months without refrigeration. In the past, I tried pickling eggs, (YUCK), Freezing eggs, and even had a friend freeze-dry some, but each method changed the egg’s structure in some way and limited what I could use the eggs for. Glassing, however, preserves the egg in its raw form making it as easy to use as a day-old egg. Interested in giving it a try? Here’s a complete guide on how to glass eggs for storage during the colder months.
What is Water Glassing?
Water glassing is an age-old preservation technique where fresh, unwashed eggs are stored in a solution of water and hydrated lime (calcium hydroxide). This creates an environment that seals the eggshells, preventing air and bacteria from entering. If done properly, water-glassed eggs can stay fresh for 6-12 months and even longer in some cases. It is important to note you can not use washed or sanitized eggs this way. So, store-bought eggs are out. For this method to work, the protective layer on the eggshell must remain intact. Dry brushing can be done to remove any dirt if needed.
Materials Needed
Fresh, clean, and unwashed eggs (ideally from a backyard flock or trusted local source)
Hydrated lime (also known as pickling lime or calcium hydroxide) – food-grade only
A large, food-safe container with a lid (glass or ceramic are great options)
Water (filtered or distilled if possible)
Step-by-Step Guide to Water Glassing Eggs
1. Gather Fresh, Unwashed Eggs
The eggs must be clean but unwashed because washing removes the natural bloom, a protective coating that prevents bacteria from entering the egg.
Only use eggs that are no older than 24 hours if possible. Any eggs with cracks or damage should be excluded as they won’t preserve well in the solution.
2. Prepare the Lime Solution
Mix one ounce (by weight) of hydrated lime per quart of water. For example, if you’re using a gallon container, you’ll need about four ounces of lime and four quarts of water.
Stir the solution until the lime is completely dissolved. The water will become cloudy, which is normal.
3. Store the Eggs in the Solution
Gently place each egg into the limewater solution. Make sure there’s enough solution to fully cover the eggs by at least an inch or two. As you add more eggs over time, ensure they are fully submerged to keep them safe from bacteria and oxidation.
If using a lid, seal the container loosely so air can escape. Place it in a cool, dark place like a basement or pantry where the temperature remains relatively steady.
4. Maintain the Water Level
Periodically check the water level to ensure that eggs are fully submerged. Top up the lime solution as needed to keep them covered.
Storing and Using Water-Glassed Eggs
Eggs preserved in this way should be stored in a cool, dark place, ideally between 50-60°F (10-15°C). When you’re ready to use them, rinse off the limewater and use them just like fresh eggs.
Note: Due to the preservation process, the egg whites may be slightly thinner, but water-glassed eggs can still be used in scrambled eggs, baking, and cooking.
Safety Tips
Only use clean, fresh eggs that have not been washed.
Avoid storing eggs in limewater at high temperatures, as this can spoil them.
Discard any eggs that have an off smell when cracked open.
Benefits of Water Glassing
Saves Money: During winter months, when egg prices tend to rise, having a preserved stock of eggs can be a money-saver.
Reduces Waste: If your hens produce more eggs than you can consume in the warmer months, water glassing prevents waste.
Provides Self-Sufficiency: This method allows you to rely less on store-bought goods and stay more self-sufficient.
With water glassing, you’ll be able to enjoy eggs throughout the winter, knowing they’re preserved naturally and safely!
