Tie the tongue tip tightly with cotton string.
Boil the water for the brine with salt and sugar and then cool it.
Place the tongue tip in the cooled brine and cure it for 4 days in the refrigerator.
Then, take the tongue tip out of the brine and place it in a pot.
Cover it with water and bring it to a boil.
Skim off impurities with a slotted spoon and then add coarsely chopped vegetables and spices.
Simmer the tongue tip on very low heat for about 1½ hours until it's fairly tender but not too soft, as it needs to be cut into thin slices.
Let the cured meat cool in the brine in the refrigerator until the next day.
Take the cured meat out of the cold brine, wrap it in plastic wrap, and store it in the refrigerator until ready to use.
