Whiskey and Raisin, Apple and Potato Tart/Pie

This is a deep filled tart ideal for Saint Patrick's Day.  Omit the raisins and whiskey if you prefer.  Potato pastry has a chewy texture.

 The jam sugar helps set the juices from the apples so the pastry isn't soggy (wait for the tart to cool slightly before cutting to aid this process).

Add blackberries instead of the raisins to make a blackberry apple tart.

Ring used is 16cm or 6 inches.

Potato pastry
255g salted butter at room temp
270g floury potato, cooked and skin removed (I use Roosters )
360g plain flour
135g sugar 45
1 tsp cinnamon
brown sugar and egg wash/milk for top

For the filling
cinnamon
raisins or sultanas
whiskey
jam sugar and butter
2 large cooking apples brambly  approx. peeled and sliced

For the filling
Soak the Raisins or sultanas  in Whiskey overnight (I gauge amount by eye-don't weigh).  Drain before using and keep the remaining Whiskey to add to custard or cream for serving with the tart.

For a firm apple filling; coat the apples in the jam sugar and cinnamon, and sprinkle a good layer of jam sugar  on the base of the pastry before adding the apples and raisins in layers, dotted with some little  knobs of butter

For a less firm filling; gently saute the apples in a little butter and jam sugar and allow to cool before adding the the pastry case.

For the pastry

Mash the potatoes very well or pass through a mouli or ricer.
Add the potatoes to the flour, sugar and spice.
Rub the butter into the dry mixture and bring together into a dough.
Allow to rest in the fridge about 40 minutes before rolling out and lining a buttered  ring
Place the pastry case in the freezer for about 40 minutes

Assembly
Preheat over to 170C fan and fill the case with apples and raisins as detailed above and top with a pastry lid or weave on a lid.

Brush lid with egg wash or milk and sprinkle with sugar and place in the oven for about 45 minutes.

Wait for the tart to cool slightly before removing the ring or cutting as the jam sugar needs time to set.

Serve with custard, icecream or cream to which you have added your reserved Whiskey.

Happy Saint Patrick's Day
