ISINGLASS | A Forgotten Way Of Preserving Eggs /Video

Learn how to preserve your eggs for up to a year without refrigeration!

How Long Before Eggs Spoil?

The average egg only lasts about 3 weeks before it goes bad. This is due to the egg white and the yolk being two different types of water, which causes bacteria to grow. Refrigeration slows this process, but does not stop it. Therefore if you want to keep your eggs longer you have to consider other storage options. Of which there are many. The method we’ll be discussing today is Isinglass.

What Is Isinglass

Isinglass is a gelatinous substance derived from the swim bladders of certain fish. It has been used for centuries as a method for preserving eggs, and will allow them to last up to a year unrefrigerated. The eggs are placed in a solution of isinglass and water, and then sealed in an airtight container. The isinglass acts as a preservative allowing for a shelf stable egg. It’s worth noting that Isinglass and Waterglass are two different methods. Water Glassing eggs is another great technique, but not the one we’re covering here. Keep an eye out as I’ll do a video and article on it too in the near future.

Kind Of Eggs Needed For Isinglass Preservation

In order to preserve eggs in isinglass, you will need to use fresh eggs. Do not use store bought eggs for this as the processes they go through are not conducive to this method of preserving. The eggs must also be free of cracks or shell damage (as any egg you eat should). Do not refrigerate or wash the eggs prior to preserving them. The eggs are laid with a protective coating that you want to leave intact as it assist in the preservation process.

The Process For Preserving Eggs With Isinglass

The process is relatively straight forward. You can watch the video below where I walk you through it, but here are the steps to preserve your eggs.

1. Fill your pan with enough water to fill the jar you will be using for storing your eggs.

2. Heat the water us and begin to dissolve the Isinglass into the water.

3. In the meantime place your eggs (ideally pointed side down) into the jar

4. Once the Isinglass is dissolved allow the water to cool some. The idea here is that you don’t want the water to begin to cook the eggs, so you need to let it cool down to just above room temperature. That said when it cools enough it will begin to set to an almost gelatin like consistency. So you need to find that sweet spot of temperature. It’s not as hard as it sounds as long as you keep a close eye and transfer it before it sets.

5. When cooled enough add the Isinglass water mix to the jar of eggs. Ensure all eggs are completely covered.

6. Allow to cool down and set to gelatin like consistency.

7. Put the lid on and store the eggs in a cool dry location like your pantry.

That’s It. Pretty simple right!

How Do Isinglass Eggs Taste?

Many claim that using this method of storage gives the eggs a bit of a chalky taste. As such this is not the ideal way to store them if you wish to eat the eggs outright, however they are perfect in recipes and do not affect the taste there.

So How Long Do The Isinglass Eggs Last

Using this method your eggs should store for 6 months to a year
