HOW TO PRESERVE EGGS: The best time to preserve eggs is August or September. The eggs must be very fresh even of the same day if possible. The eggs are placed in a cask containing crumbled fodder, allowed to tool and then covered completely. This will keep the eggs fresh for months. If you want to keep them for more than a year, place the eggs in earthware crock & cover them with a 10% lime solution. Cover tightly to keep the air out and store in the wine cellar.
