How it works
Papain is a protease from papaya. There’s most of it in the milky sap of the green, unripe fruit.
It’s the working part of many powdered meat tenderisers: sprinkle it on, and it starts snipping the meat’s proteins before the pan does.

Far-out fact
Papain is why some meat tenderisers work: it snips meat proteins before you cook.
