i am making pork loin and i want it to be tender and flavorful without losing a lot of moisture, my go to method is to Dice the pork loin into bite sized cube, then chop onions into very small pieces and mix it in well with the pork loin, then i add 40% water, 40% rice vinegar, and 20% soy sauce to the mix (about 2 cups in total liquids), then i throw in some chopped mushrooms on top, compress the cold mixture, and cover it with lettuce to reduce evaporation and prevent oxygen flow. is this a bad way of doing it? i made it up myself so im not sure, can anyone give me some decent advice on how to make it better, i plan to simmer it in the marinate afterwards, along with garlic and parsley,
