I don't make sorbets much, the truth is sorbet for me is just an adults slush puppy and ice cold zingy lemon does not always appeal to me, but my husband loves the stuff so its for him I oblige, even when it is raining and ice cold outside.
You will need a food processor for this recipe.
Juice and zest of 5 unwaxed lemons
1 3/4 pints of water
Sprig of fresh rosemary
Gently bring everything to a boil, stirring frequently until all the sugar has melted. Simmer for a couple of minutes, then remove from the heat and leave it to cool. when cool, strain and discard the zest and rosemary sprig.
When cool enough, pour into a suitable plastic container and freeze. Freeze, then after an hour take out of freezer and blend in food processor, pour back into container and freeze for another hour or so, then remove from freeze and blend again. This is to ensure that there are no mass of ice, but soft crystals. Then freeze. Twice should be enough, but you may want to do it a third time if you want softer crystals.
