This fabulous rhubarb custard pie is adapted from a vintage recipe leaflet from Washington State Rhubarb Growers. It's such a simple recipe, and if you use a frozen or ready-made pie crust, it takes no more than 15 minutes to prepare. A small amount of nutmeg adds flavor to the pie but feel free to use ground cinnamon instead.

The all-butter pie crust is easy to fix with a food processor, but you can cut prep time by about half if you make the pie with a frozen pie crust. Feel free to use frozen or homemade pastry, or use refrigerated pie pastry sheets.

Serve this pie at your next cookout or take it along to a potluck dinner. This is a fantastic way to use fresh rhubarb, and your family and friends will love it. It's no wonder rhubarb was once called "the pie plant!"
