When May arrives, I start looking for rhubarb in the store to make a pie. This Rhubarb Custard Crumble Pie is one our family loves. Filled with tart rhubarb and a custard filling, then topped with a sweet crumble. It’s especially delightful with a dollop of whipped cream on top.
I began making Rhubarb Custard Pie when I was newly married and used Grandma Vogts’ recipe. At that time, I placed a second crust on the top. It was good, and we all enjoyed it. Since then, however, it has gone through a few revisions. Instead of a top crust, I now use a crumble, and I have also added more custard sauce to the recipe, as the old one was always pretty thick.
My Grandma Swiler was always intrigued by the rhubarb custard combination, and we had many conversations about it. I think she would have liked this recipe.
As a girl, my mom and grandma always had rhubarb in their gardens, so when the end of May arrived, it was time to harvest the long stalks of green vegetable. Yes, rhubarb is a vegetable, despite it’s use in pies, jams, and other desserts. And our garden rhubarb was always green, not the pretty red rhubarb that you find in the stores.
If you’ve never tasted rhubarb before, it’s quite tangy. So, sugar is always required when working with it, whether you’re making a pie, a crumble, or a sauce to put over ice cream. I recently saw a recipe for rhubarb scones, and I’m eager to give that a try. I’ll be sure to report back if it turns out well!
When browsing rhubarb recipes you may find those that include other spring fruits, such as strawberries or blueberries. These two fruits go really well with the flavor and tartness of rhubarb, especially when made into a crumble, crisp, or pie.
