Note: To make the toasted papaya seeds: Cut open a papaya and scoop out the seeds. Place a handful of said seeds on a kitchen towel. Fold the towel over to cover the seeds and rub vigorously with your hands until the sticky membrane has slipped off. It's ok if some of it remains, just get them as dry as possible. They should look like tiny black peppercorns. Heat an 8-inch skillet over medium heat for 1 minute. Add the seeds and toast, shaking the pan frequently, until they begin to pop, about 2 minutes. Remove to a plate and season generously with salt. Delicious.
