Blend together the honey or maple syrup, coconut cream (using only the hardened part from the can with none of the liquid), lemon juice (fresh from lemons) until fully smooth. Taste and see if you'd like it a little sweeter.
Pour the mixture into an ice mold and freeze until fully frozen (about 2 hours, but I prefer to make it in advance and let it freeze overnight).
Add the cubes to a blender and blend on low adding 1 tbsp of milk or creamer at a time until it blends and is smooth. You will likely need to use the stick from your blender to press down the contents or (with the blender turned off) scrape the sides frequently. Patience is key here!
If using right away: Spoon the lemon sorbet into a container with a lid to keep in the freezer for 15 minutes to chill.
If using at a later time: Spoon the lemon sorbet into a container with a lid to keep in the freezer until ready to use. Note that if kept in the freezer, it will get pretty tough to scoop. Aim to let the sorbet thaw for 5 minutes or so until scoop-able.
To finish them, fill the prepped lemon shells (if using) with the sorbet and top each with the lemon top "lid" and a little basil to look like a leaf. If not using the shells, scoop the sorbet into a bowl and enjoy as is!
