If there is space, you can put another piece of meat on top, then seal the jars tightly with the lids.
Place a cotton cloth on the bottom of a large pot.
Then, place the jars with the meat side by side in the pot.

Fill the pot with water until it covers the lids of the jars and cover the pot.

After this time, uncover the pot, let it cool, then remove the jars and dry them thoroughly.
Once completely cooled, the juice released by the meat will have a gelatinous consistency.
Store in a cool, dark place, where the temperature does not exceed 10 °C.
