Transfer the yolk sauce to a measuring cup - like OXO - it will be more convenient.
Arrange side by side the Calcium Chloride Solution, the Sodium Alginate Solution and the rinsing bath.
Keep at hand: measuring tablespoon, a standard tablespoon and a timer.
Creating The Membrane: dip a measuring spoon in the Calcium Chloride Solution; Shake the spoon gently; pour into it yolk sauce - This will make it easier to shape a yolk; Immerse the spoon in the Calcium Chloride Solution gently, facing up - for about 30 seconds (this way the yolk doesn't fall out). Turn the spoon gently (when inside the solution) and release it from the yolk.
After about 20 seconds, turn it carefully to make sure the yolk is evenly coated. Don't touch the yolk directly, but "make waves" around it - pushing the surrounding solution with a standard spoon - the yolk will turn over like a fetus in the womb (sorry for the image, I couldn't help it :)
Leave the yolk in the Calcium Solution for another 10-40 seconds; It is not recommended to leave it in the solution for more than a total of one and a half minutes.
It requires some practice - but don't worry - after several attempts, you too, will acquire the technique - I promise!
Using a standard spoon carefully remove the yolk from the calcium chloride solution, Make sure to drain the rest of the calcium chloride solution from the spoon, so that only the yolk will remain in the spoon without any liquids, then transfer it to the Sodium Alginate solution. After about a minute turn the yolk carefully so that the yolk is evenly coated with the solution. Don't touch the yolk directly, but "make waves" around it - pushing the surrounding solution with a standard spoon until the yolk flips over.
Leave the yolk in the Sodium Alginate Solution for a total of 1-3 minutes - no more.
Please note: It is essential, at least initially to work with a timer. Otherwise, the yolk may thicken/harden too much. On the other hand, too little time will not be enough to create a sufficiently durable membrane.
Gently transfer the yolk, using a standard spoon to the pre-prepared rinse bath, to wash away the excess solutions. Turn carefully to wash it off all sides. Keep the yolks in the water until use. It is not recommended to leave them in the water for more than an hour - they may lose their texture.
