This is the second time I've made this pie, and I'm pretty thrilled with the results. I added just a bit of vanilla (1/2 tsp.?) and a tiny squeeze of lemon juice as well. As far as taking more work, I don't really think it matters--it's only about another five minutes, and the results far outweigh that extra time. I would, note, though, that I'm using a rather deep pie dish, and next time I make this, I plan on adding another half-recipe's worth of the berry filling. It seems a bit thin for this deep dish. Thanks for sharing!

What a great recipe! I made this today for Easter at my Dad's with blackberries I had frozen from my blackberry bush last summer. I used FarahC's Crumble Topping for the topping and the pie was a huge hit with no leftovers. Thank you

Wonderful recipe for my favorite blackberry pie. This recipe takes a little more time, but it is time well spent. No one turns down a piece of this pie.
