When life gives you lemons

When life gives you lemons, squirt them on your apples and make pie!
One of our friends has the daunting task of remolding an old home from top to bottom and this weekend Josh is helping him make their laundry room critter proof. I rarely remember details about our friend's likes and dislikes and have even saved those silly emails about fav. movies and such to review periodically to help me out. Yesterday though my brain had a hiccup and reminded me that Jason loves fruit pies. His wife Marianne does not, but she is out of town so tonight we shall feast! Jason is from Iowa, where Rhubarb is a staple and so in addition to the apple pie I also made a Rhubarb/Strawberry Pie.
mmmmmm,
sweet and tart!
The apple pie recipe was one my sister found and generously shared with me.
