Papaya as a Meat Tenderizer
Papaya is an excellent natural meat tenderizer. Use papaya (ripe or unripe) on tough cuts of red meat and the enzymes in the fruit will help break down the collagen, leaving you with a tender steak.
To use it, peel off the skin, slice in half, scoop out the seeds, and puree. Spread it over the meat, chill for three hours, then scrape off the puree and cook.
