Soften coconut sorbet in mixer; pack into center ofmold; smooth top of bombe. Cover with plastic wrap, and freeze overnight, or up to 1 week. (To create a layered bombe, measure the amount of water your mold will hold to determine how much sorbet you will need. Spread the first layer into bottom of mold and smooth; freeze until firm, about 1 hour. Then add the next layer, freeze again, and repeat.)
To unmold, dip mold in hot water to slightly melt outer layer. Invert onto a cake stand, and remove mold.
To serve, cut into slices with a knife (if necessary, dip knife in warm water for easier cutting).
Packing the mold: Use a rubber spatula to press sorbet up against sides of mold; an offset spatula works well for smoothing the surface. Freeze each layer about 1 hour before adding the next. Return to the freezer for up to 8 hours after removing mold.
