In Mexico, papayas are served with a wedge of lime and a pinch of salt. This sorbet honors the sweet-tart combination and transforms it into an elegant dessert. It's like a tropical vacation in your mouth.
Make Ahead Tip: The sorbet will keep in the freezer, without freezing solid, for up to 3 hours. (Alternatively, prepare through Step 3, transfer to a shallow pan, cover and freeze for up to 1 month. Before serving, let defrost for 30 minutes, break into small chunks and process in small batches in a food processor until smooth and scoopable.)
