Where to buy prepared pastry dough?
Trader Joe's carries both frozen pie dough and puff pastry dough. I find their pie dough harder to work with and find it easier to make my own, although as taste/texture goes TJ's is pretty good. Their puff pastry (season but around right now) is excellent. The only ingredients in it is flour, water, butter, yeast, salt and sugar. I find it disappears quickly, though, so stock up when I see it.
Was there another type of pastry dough you were looking for?
