You asked if it would take more than 3 minutes to cook pork liver with soy sauce, right? Yes The home version of pork liver sauce is very simple. It needs to soak the pig liver in clear water for three hours, boil the water, blanch the soaked pig liver in boiling water for five minutes, take it out and rinse it with clear water. Blanching for less than 3 minutes will leave blood foam in pig liver. If it is too short to cook thoroughly, it will harden and affect the taste. Five minutes is the best.
