Insert the gelatine sheet in cold water for 10 minutes.
For the strawberry water, blend fresh strawberries with 10% of water.
In a saucepan combine cream, sugar, strawberry water, orange zest, fennel pollen and the vanilla stick previously opened in two. Set over medium to high heat for 15 minutes stir every 2 minutes.
Strain the liquid.
Add the gelatin sheet previously hydrated in water and mix well with a stick blender or a whisk, until the gelatin sheet is completely dissolved.
Let the preparation cold down for 10 minutes then pour into the mould or a rectangular tray 10 mm high.
