Rhubarb Custard Pie

Here’s a classic rhubarb recipe to add your summer baking schedule, the Rhubarb Custard Pie! Adapted from American Cookery by James Beard.

Where would we be without the sweet moments of summer? The first ripe peach, the best strawberries, and of course all the rhubarb you can ever use.

I am a huge fan of rhubarb for many reasons, not only because it’s SO abundant but it’s also so incredibly easy to use. And as far as I know, no one ever gets tired of rhubarb desserts.

Be sure to remember when you’re freezing it to look at your family’s favorite recipes and freeze it in THOSE amounts so you have enough in each bag for each recipe. It’s SO handy to have is frozen in the perfect sized bags.

Pie Crust!

For this Rhubarb Custard Pie your best bet is to make a fresh homemade pie crust! I know that sometimes people feel overwhelmed with making pie crust but it is SO EASY.

Use my Easy Pie Crust recipe and you’ll see just how easy a homemade pie crust is! BUT if that seems like TOO much work you can ALWAys use a store-bought crust or a mix. Someday you do need to tackle the pie crust though!
