Hello there! When preparing a hearty meat pie for your family, both doughs have their merits, but they serve different culinary purposes.
Yeast dough creates a sturdy, bread-like crust that is traditional for homestyle meat pies. It absorbs savory juices well and provides a filling, substantial texture.
Puff pastry yields a wonderfully flaky, buttery crust, which is lighter and crisps up nicely, though it is less traditional for heavy meat fillings.
I recommend yeast dough for a classic, robust meat pie, but puff pastry works if you want a lighter top crust. I hope your family dinner turns out wonderfully!
