This was absolutely delicious! I followed the recipe...until I was about to pop it into the oven...using a half of stick of butter, I put pats over the top..the topping just looked a bit too dry to me, so I had to add a little more butter. (I actually wouldn't have minded using the whole stick!!! I'm a Paula Deen-type!!) Will definitely make this next time I want a blueberry dessert!
i add lemon juice to the blue berry mixture
