You will need:
Make the filling first.
1kg of grated zucchini. I used one large zucchini. This works better than several small ones as you really need the moisture that is contained in a large fruit.
200g of uncooked rice. Do not be tempted to use cooked3 eggs
Mix all of the ingredients up in a bowl and then get on with the pastry.
300g plain flour50g butter
1 tsp salt
Rub the butter into the flour until it resembles fine breadcrumbs. Add enough tepid water to make a smooth dough and then roll out 2/3 of the dough straight away to line a tin about 40cm x 20cm. This does not need to be exact. Leave an overlap all around the tin so that you can flip it over the center .
Fill the pastry with the filling. It will be very liquid. Use it all. Do not strain out any of the liquid.
Roll out the remaining pastry and cover the top of the mixture. Flip the pastry over the center piece and put into a hot oven about C190 for about 45 mins. It should be lovely and brown on top and perfectly cooked underneath. If it is not leave in the oven for a few more minutes.
