Has anyone done it? While buying Dellzeq's recommended culinary delight in an asioan supermarket I came across some tins of halal corned beef which means that I can make a halal corned beef an onion pie for one of my muslim colleagues. The tinng is I've only used lard based pastry in the past and that's a non starter for the proposed pie. Does vegetable fats e.g. Trex work? I don't want to waste pie making time unnecessarily.
