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!
