In a food processor, mix together flour and salt. Add butter, pulsing until the mixture resembles coarse meal.

Add water 1 teaspoon at a time, process just until dough clumps together and begins to form a ball.

Flour your surface and roll out dough.

Line a baking sheet with parchment paper and place rolled pastry on top.

Heat the sugar and water together in a saucepan.

Once the sugar is dissolved , stir in the fennel and apple. Bring to the boil then reduce heat and simmer until softened. Stir in cornstarch.

Spoon mixture onto rolled out dough. Slowly draw the pastry towards the center of the mixture. Garnish with fennel fronds if desired.

Bake in pre heated oven for 20-25 minutes or until golden brown.

Serve with freshly whipped cream or vanilla ice cream.
