So. Boil salted water in 2 pans. Salt should be enough. One pan, set aside. Another must boil on medium heat. Fold the sheets of a stack of 15-20 pieces.

Put the leaves in the boiling solution for a few seconds. Bright green leaves will change color to olive.

Remove the leaves with a fork and place in clean sterilized jars.

Tamp them with a wooden spoon.

The sheets can be folded twice. When the jar is full, pour on top of salt water from the other pan and close the lid. Sterilizing is not necessary. But if you have a little dense leaves, and can be sterilized for 2-3 minutes. It is convenient to use half-liter jars. The leaves should be thin, without pubescence on the reverse side. Collect young leaves of medium size. That's all good luck to you!
