Water glassing eggs with hydrated lime (long-term egg storage)

The lime solution helps shield eggshell pores from air and bacteria, keeping properly glassed eggs usable for months; long storage can produce subtle changes in odor or flavor. In a long-term preparedness situation, fresh eggs are one of the most valuable protein sources you can stockpile without electricity. A single bag of food-grade lime and a bucket can preserve hundreds of eggs for a year or longer.

• Calcium Hydroxide, food-grade pickling lime only (not construction-grade hydrated lime)
• Clean, chlorine-free water (well water, filtered, or distilled; or tap water left uncovered for 24 to 48 hours so the chlorine off-gasses)
• Fresh, unwashed eggs (never previously washed or scrubbed; store-bought washed eggs will not work)
• Food-grade container with tight seal (glass crock, ceramic, or food-safe plastic bucket)
• Measuring scale or spoon

1. Gently wipe each egg with a dry cloth or soft brush to remove any dirt or debris. Do not wash; the bloom must stay intact for water glassing to work. Check each egg for hairline cracks first: lower it into plain water and watch for a stream of fine bubbles, or hold it up to a bright light to candle it for fractures. Set aside any cracked egg, since even a fine crack lets bacteria into the whole batch.
2. Choose the right ratio for your batch size: 1 oz lime per quart of water (about 8 eggs), 2 oz per half gallon (14-16 eggs), or 4 oz per gallon (about 28 to 32 eggs). Do not overpack; the eggs all need to stay fully submerged.
3. Mix calcium hydroxide into chlorine-free water and stir until uniformly cloudy. This cloudiness is normal and means the lime is properly suspended.
4. Place eggs pointed-end down in the container. The natural bloom on the shell is a protective coating that the lime solution reinforces, so handle gently.
5. Pour limewater over the eggs until they are fully submerged, with at least 2 inches of liquid above the top layer. Seal the container tightly.
6. Store in a cool, dark place (pantry, basement, or root cellar). Check monthly to ensure eggs remain submerged; top off with more limewater if the level drops.
7. Lift out the eggs you need and rinse them well under cold running water to wash off the pickling lime. Before using one, run a float test: set the egg in a bowl of plain water, where a good one lies flat on the bottom, an older but still usable one tips upward, and one that floats has built up gas inside and should be discarded, as should any egg with a sulfur smell. Crack each into a bowl to check before cooking. Glassed eggs are best fried, scrambled, or baked; if hard-boiling, prick the shell first, since glassed shells can crack.

Store in cool (50-70°F), dark, dry conditions. Kept properly submerged, the eggs last up to 2 years, with the best quality in the first 12 to 18 months. Before use, inspect for cracks, odors, or discoloration. Best container: sealed glass or HDPE container. Avoid metal (corrodes when moisture is present). See the Containers section.
