Boiled tongue in soya sauce

If you buy the tongue from the butcher raw, boil it first for 2 hours and leave it to cool in the stock. When it is cool, skin the tongue and cut off, in slices, the 500 g that you need for this dish.

Peel and slice finely the shallots and garlic. Heat the oil in a wok or saucepan, and fry the shallots or garlic until soft. Add the ground ginger, nutmeg, tomato purée and the sliced tongue. Stir, then add the soya sauce and a little salt and pepper, and the water. Simmer for 3 or 4 m
