Preparation

• Cut off the top 1/3 of the lemon (not the stem end) and reserve for the 'cap'.
  Hollow out each lemon by using a grapefruit knife just inside the rind and circling the flesh (being careful not to puncture the lemon). Remove juice and flesh and put it in your juicer.
  Make a slight shallow cut on the bottom of each lemon shells (being careful not to cut through to the inside of the lemon). This will make them sit straight and not fall over when placed on a plate.
  Freeze the shells at least one hour or overnight. Then fill with sorbet and freeze again. this sorbet can be made ahead and will keep several days in the freezer. The frozen shell will prevent the sorbet from melting too quickly when you serve it.
