Last year I fell in love with Strawberry Rhubarb Pie, so much that it’s in the running for my favorite pie of all time! There is one secret ingredient that I find make it super delectable, you can find it in the ingredients list.

And of course I use my favorite Pie Crust Recipe, which you can use too. If I make my pies out of any pie crust other than Grandma Tillie’s Pie Crust Recipe, my husband says the pies are ruined, yes, he’s that picky, and this is his Grandma’s pie crust recipe. In fact, she’s the one who taught me how to make pie crust, so it’s special to me too.
