Eggs can be a bit ‘feast or famine,’ but egg gluts are a blessing in disguise. When you have your own backyard flock, the supply of eggs depends on the season. Chickens are not designed to lay all year round without us tricking their bodies with artificial lighting. This makes it important to have several methods for storing and preserving fresh eggs. Here are five effective methods to store and preserve your eggs:
1. Refrigeration
Refrigerate your eggs at or below 4°C (40°F) to slow down bacterial growth and prolong their freshness. The high humidity also prevents moisture loss. Eggs can typically last for several weeks when refrigerated. It's advisable not to wash them first as it removes the protective bloom. Keep them in the main body of the fridge to avoid damage from the motion of the door.
2. Coating with Oil
Using coconut or food-grade mineral oil creates a barrier that helps seal the eggshell, preventing air and bacteria from penetrating it. Gently warm a small amount of coconut oil and brush it on eggs or smear with freshly washed hands until completely covered in a thin layer. Store pointy end down in an egg tray or box and label it with the date. Store in a dark, cool place for up to several months.
3. Pickling
Pickling eggs involves hard boiling and shelling them, then submerging them in a solution of vinegar and spices. The acidic environment kills bacteria and excludes air, allowing pickled eggs to be stored in clean glass jars in the cupboard for several months. Place hard-boiled eggs in the fridge overnight before pickling to make it easier to remove the shells.
4. Freezing
Eggs can be frozen, but freezing changes their texture. Crack them into a container, gently beat them, and freeze in ice cube trays or other suitable containers. Once frozen, transfer them to a more convenient container. Alternatively, separate the yolks and whites before freezing. Add ½ teaspoon of salt or 1–1½ tablespoons of sugar per 240ml of raw egg to prevent yolks from gelling. Use frozen yolks within a few months for best results, though they can be stored for up to 12 months.
5. Water Glassing (Sodium Silicate Preservation)
Water glassing involves submerging fresh eggs in a solution of water glass (sodium silicate) and water. This method creates a protective coating around the eggshell, preserving the egg for several months when stored in a cool, dark place. They can be used like fresh eggs, but some people say water glassed eggs have an odd taste if the lime solution penetrates the shell. Note that this method carries a higher risk of botulism and is generally not recommended for food safety reasons.
Final Tips
- Ensure eggs are as unsoiled as possible before starting by keeping the nest box clean and dry.
- Always check eggs for cracks by holding them up to the light and never preserve an egg or its contents if the shell is damaged.
- Preserve your very freshest eggs for the best and safest results.
- Backyard flocks are statistically more likely to carry Salmonella than commercial birds. To minimize risks, buy vaccinated hens, use probiotics regularly, and avoid keeping hens with ducks.
By employing these methods, you can effectively store and preserve your eggs, ensuring a steady supply even during off-laying seasons.
