I had decided to make Wild Blackberry Pie Squares, so I got to work on putting the crust together. After I was done with that, I went to wash the blackberries. That’s when I noticed a tiny white worm munching its way through one of our beautiful berries. I picked that berry out of the bunch, hoping that was the only one, then scoured the rest of the berries very carefully. That’s when I noticed another, then another, and another.
I yelled out to my hubby, “These berries are full of worms!!” He was so heartbroken, and so was I. Those berries looked so delicious, and I had already made my pie crust, which was just sitting there, waiting to be covered in beautiful wild blackberries.
Angrily, I tossed the blackberries in the garbage can. John knew how upset I was. I was already having a bad day, and this was just the icing on the cake. So, he offered to go to the store to get more berries. He was going out to pick up a pizza anyway, because I had burned our chicken dinner. Like I said, bad day. I also woke up this morning, COVERED in mosquito bites from our little adventure outside yesterday.
When John came back from the store, he delivered a package of blackberries, a package of raspberries and a package of blueberries to me. He said the blackberries were a bit on the expensive side, and the raspberries and blueberries were cheaper, so he just decided to get a package of each of those instead of three packages of blackberries. That was fine by me. I’ll never turn any kind of berry down!
I actually think the mixture of berries adds a depth of flavor to these pie squares, that wouldn’t be there with just a single berry. If you want to use just a single berry, that would work well too though.
