It's an all rounder, britwife. Works for anything. I've stuffed the smaller pastry ones with potato curry type filling, or I've made fruit pies, I even made them for my mom last time I was back home, when she showed me how to make the crust, and she was impressed at how the pastries turned out. The thing I like about it is, you don't have to mix it with your hands, so no floury mess. The crust is really flaky and light and yummy. When we were kids, we used to joke that the only pie crust we would eat was our mom's. Any other pie we would leave the crust edge on the plate. Just use regular veggie oil. The liquid kind, not a solid like crisco.
*edited to add* when you add the milk to the oil, at first you think it's not going to work, because the oil and milk seperate. Don't bother with how the liquid looks, as long as the measures are right, it'll be ok. just mix in the dry ing. and start stirring. Also, after rolling it out, it can be kinda delicate...if it starts to come apart on the edges, just pinch it back together.
