2, soak in rice vinegar (add a little salt, sugar moderate, ginger slices a number of) for 2 hours;
3, the first to funnel out of the rice vinegar, add cornstarch (or cornstarch), a little dark soy sauce to be used;
4, cook the pig's feet through the fire, add the rice vinegar listed in item 3 to stir-fry, hooked into the peanut oil
Making method two:
1, scald the pig's feet with boiling water, then cut them into pieces and wash them with cool water (no oil is the best);
2, soak them in rice vinegar (with a little salt, moderate sugar, and a number of slices of ginger) for 4 hours;
(can be used directly.)
The above methods are for reference. Others are welcome to provide better methods. Of course, the general hotel practice is not so, and even some people use hydrogen peroxide to make, I do not support!
