Last night, I cooked sinigang na pata. Cooking this part of pork will really take time to make it tender. I remember about Papain – the natural meat tenderizer. So, I added few pieces of papaya seeds and it really worked!
Therefore, next time you buy papaya, don't throw the seeds away. Air-dry them and place in an air-tight container. Add few amounts if you want to make the meat tender faster.
By the way, papain has the ability to break down meat fibers. This is also used as ingredient in powdered meat tenderizers in the market.
