Pour the water over the dried willow bark in a saucepan and simmer for 10 minutes. Strain out the bark and return the liquid to the pot, simmering uncovered until reduced to about 2 1/2 cups, 20 to 30 minutes. At this stage, the mixture will be intensely bitter, but do not let that faze you; sugar and limes can cover a multitude of sins.
Remove from the heat and stir in the sugar, orange blossom water and lime juice and zest and let cool. Once cool, place in a covered ice-cream tray and freeze.
For adults, to relieve the pain of a headache, eat about 1/2 cup (an ice-cream-scoop-sized dose) up to 3 times a day.
Anyone who is allergic to aspirin or any other anti-inflammatory drug, or who suffers from an ulcer or has asthma, should not take willow bark. Do not take if you have been warned not to take aspirin by your doctor, or if you are pregnant or breastfeeding. Children and adolescents under 16 years should not take willow bark either. If you are taking any other medication, check with your doctor or pharmacist first.
The granita will keep for up to 1 year in a freezer.
