Preserving Eggs a Year

Ingredients

Directions

Make the brine

  1. Dissolve the salt and lime in boiling water.

  2. Let the mixture settle.

Preserve the eggs

  1. Place the eggs in stone jars and cover them completely with the liquid. Ensure the jars are made of stone, not soft crockery.

  2. Store the jars in a cool place; the eggs will keep for twelve months.

What each ingredient does

Eggs
The main food being preserved; the whites set into a firm gel as they cure.
Common salt
Draws out moisture and inhibits spoilage microbes, helping the eggs keep.
Lime
Makes the liquid alkaline, which helps preserve the eggs and firms the whites.

The step that matters

Cover the eggs completely with the liquid. Any part of an egg left exposed to air can spoil, and the preserving effect depends on the brine covering every egg fully.
