Keep those seeds!

They taste like a combination of black peppercorns and mustard seeds. Wash and let them dry naturally for a few days in a warm place then put them into an old pepper grinder to use as seasoning. Don't grind them all at once as they're better freshly ground. Excess can be stored in the freezer. Just take out a tsp at a time and use it as you need it. When kept frozen, papaya seeds can retain their nutritional value for 6 to 12 months. Defrost in the fridge overnight before use
