Frugal fun: easy pastry

Bit alarming, this one but bear with me.

Ingredients:
100g value plain flour
pinch of salt
3 tbsp vegetable oil (could use olive oil but that would be less frugal)
1 tbsp cold water or perhaps a little more, depending . . .

Method:
Place the flour and salt in a bowl and make a well.  Pour the oil into the well and lightly mix with a fork.  it doesn't exactly breadcrumb but it does go into little globs.
Add the water and bring together with your hands, very lightly.

Form into a ball, wrap and chill.

Roll and use.

Of course, I had to test this so I made a jam tart.  Yes, just one jam tart, talk about a waste of oven heat although, to be fair, I had just made some soda bread so it was warm already.
And you know what - it was nicer than my pastry usually is.  Much nicer.  I was surprised but pleased.
I now have three balls of it in the freezer for pot pie toppings.
