In a mixing bowl or pitcher, whisk the pickling lime into the filtered water until fully dissolved and the liquid looks slightly cloudy.
Place the fresh unwashed eggs gently into a clean glass jar or food-grade container, arranging them point-side down.
Slowly pour the limewater solution over the eggs until they are completely submerged by at least 1–2 inches of liquid.
Cover the container with a lid to prevent contamination while allowing minimal air exposure.
Store the container in a cool, dark place such as a pantry, cellar, or basement where temperatures stay relatively stable.
When ready to use, remove an egg from the solution, rinse it thoroughly under running water, and use it as you would a regular egg.
Always check eggs for freshness by cracking them into a separate bowl before adding to recipes.
