1, soy sauce itself contains a strong sauce flavor, which is very suitable for adding flavor to this braised "big dish". Coupled with the protein contained in the pig's trotters, the soup will become thicker and thicker, and the potatoes inside will naturally become more and more delicious. Because of this, the addition of salt should be put at the end as far as possible, otherwise, if it is salty at last, adding water will dilute the fragrance;

2, potatoes are easy to oxidize and turn black after being cut, and can be soaked in water or cut into pieces. In any case, the pig's trotters must be cooked to 80% maturity, otherwise the potatoes will dissolve in the soup for too long, as well as sweet potatoes, yams, lotus roots and so on. It is also more suitable for stewing.
