Raw materials recipe:Lean meat5 pounds,Soysauce1 pound,Sugar3 ounces, rice wine 1 ounce,Fennel seeds10 grams, freshGinger20 grams.Preparation method: 1 Processing of raw meat: remove bones, skin, fat, tendons, and connective tissues, then cut the lean meat along its fiber direction into strips before cutting them into 3 cm long short pieces.2 Cooking and drying: place the prepared lean meat in a pot with an equal amount of water, then process it in three stages.First stage: cook the lean meat until it is tender.Boil over high heat, remove the floating oil, continue boiling until the meat is cooked through.If the meat has not softened and the water has already evaporated, you can add more water as needed.Once a toothpick inserted into the meat easily separates the fibers, add the seasonings and continue cooking until most of the liquid has evaporated.Second stage: the pressing stage.Use medium heat, press the meat pieces with a spatula while constantly flipping them.Be careful not to start too early or too late.If pressed too soon, the meat pieces are still tough and hard to separate, reducing efficiency;Pressed too late, the meat pieces become too soft and may burn, causing losses.Third stage: the drying stage.Use low heat, continuously flip and press lightly and evenly until all the meat pieces have separated and most of the moisture has been removed.The color will change from gray-brown to gray-yellow, finally turning into a golden yellow with a special aroma.Marrow.
