The biggest difference between sweet and sour pork slices and sweet and sour pork loin is the selection of ingredients and the preparation method. In terms of the choice of ingredients, the sweet and sour pork slices are pork belly, while the sweet and sour pork loin is tenderloin; in terms of the production method, the pork belly in the sweet and sour pork slices must be re-fried at least twice to remove the fat in the meat. The tenderloin can only be fried once because of its tight texture. In terms of texture, tenderloin is smoother and more tender than pork belly, and it tastes better and more delicious. Let me share with you the production process of these two delicacies.

1. Sweet and sour pork slices. Sweet and sour pork slices are a traditional famous dish in Shandong cuisine. First, we take a piece of pork belly and remove the skin, then cut the pork into slices about five millimeters thick, put it in a bowl, add appropriate salt and cooking wine, and stir evenly. Pour the cornstarch into a new bowl and add an appropriate amount of water until it becomes a fine paste. Then add an appropriate amount of cooking oil and continue stirring. This will increase the crispiness of the sweet and sour pork slices. Pour the marinated pork belly into a bowl and mix well with the starch. Heat the oil to 60%, and slide the pork belly piece by piece from around the pot into the pot for frying. This will not only ensure even heating, but also prevent the meat slices from sticking together. Because the fat content in pork belly is relatively high, it needs to be fried again so that it will be crispy on the outside and tender on the inside. In this way, the meat slices are processed.

Next, start preparing the sweet and sour sauce. The ingredients used here include ginger and garlic, and the seasonings include tomato sauce, white sugar, rice vinegar, light soy sauce, salt and water starch. First, cut the ginger and garlic into minced pieces, add a little cooking oil to the pot, sauté the minced ginger and garlic, then add enough white sugar and white vinegar, and keep turning the bottom of the pot to boil the sugar. Then add an appropriate amount of light soy sauce and salt to taste, continue to stir the sugar bubbles in the sauce, add an appropriate amount of tomato paste and water starch to thicken, and wait until the sweet and sour sauce in the pot becomes sticky. Finally, pour the sweet and sour sauce over the meat slices and sprinkle with a little white sesame seeds. The sweet and sour pork slices are finished.

2. Sweet and sour pork loin. Sweet and sour pork tenderloin is a very classic popular dish. The tenderloin is very smooth and tender and has the best taste. Its preparation method is similar to that of sweet and sour pork slices. After the tenderloin is sliced, salt, cooking wine and water starch are mixed, and the surface is stirred to form a slurry. Then put it into the pan and fry it twice, and finally pour it with sweet and sour sauce and it's ready to eat.
