Make the chamomile tea first so you have it ready for the next step. I used 2 tea bags.
Slice and stone the nectarines, there is no need to faff about peeling them.
Cook them in the tea (remove the tea bags first) for about ten minutes or until soft.
Now add the sugar and stir well until dissolved.
Set aside to cook completely before you blitz everything in your food processor or push through a metal sieve.
Stir in the fresh lemon juice until well mixed.
Pour into an icecream maker or just pop into the freezer and break up the crystals and give it a stir every hour or so.
