Rhubarb Custard Pie Secret? What secret? THERE IS NO SECRET.

Rhubarb Custard PieNo really, there’s not anymore. I’ve been planning my mom’s surprise retirement/birthday/anniversary party for months now and while the event itself was amazing, I’m just so glad it’s over so that I don’t have to worry about giving away the surprise anymore.

Rhubarb Custard PieI have a pretty bad track record. Once I threw a surprise party for Eric and a few hours before the event I said to him, “I have to go to the store to get stuff for your surprise party tonight” and then I caught myself and widened my eyes and slapped my hand over my mouth. He didn’t get it somehow. (??)

Later, our first guests arrived exactly when I asked them to, except he was the one to answer the door because I had yet to send him on his get-out-of-the-house-errand. I had to awkwardly make eye contact with the arrivals and say, oh you guys are just here [30 minutes away from your house] dropping by right? I seriously have no idea how he was still surprised.

Rhubarb Custard PieMy mom, on the other hand, wasn’t surprised in the slightest. No matter how old you get, you just can’t keep secrets from your mom. At least I never could. Oh well, it was an awesome party, if I do say so myself, and bonus! We have enough food leftover to feed the armies of 3 nations.

Me and my 4 siblings were all together for the weekend, which rarely happens since we’re spread across 4 states. We were celebrating her retirement after 20 years of teaching, my parent’s 40th anniversary, and her 60th birthday. That right there made up for any potential ruined-surprise deflation. Pretty hard to stay upset when there is so much awesomeness happening.

My mother-in-law Kris has been talking up this Rhubarb Custard Pie for years. I’ve never had it because I don’t visit when rhubarb is in season. I just know that it has family-legend-status. I wanted to make it for Eric’s birthday this year, so I asked for the recipe, and she texted me a photo of the recipe in her Betty Crocker cookbook. “It’s basically the same,” she said.

Except that the crust burned, the rhubarb was undercooked, and it was super runny. I asked her about it and she said, “Oh did you cover the crust? Did you beat the eggs well? Did you add tapioca? Did you up the salt?” Um, NO!!! “Oops, forgot to tell you those parts. Guess it’s an excuse to make another pie!”

Rhubarb Custard Pie

Honestly though I can’t be mad. The first one was still pretty good, and it made me appreciate the second one–perfection–even more. This it my new favorite pie. No really. It used to be this Strawberry Glace Pie, and that one is still up there, but Rhubarb Custard Pie trumps it now. I am jumping on the family-legend-pie bandwagon because this. is. it my friends.

Rhubarb Custard Pie

Serves Makes 1 9-inch pie     adjust servings


For the crust:*

  • 1/4 cup very cold water
  • 2 cups flour
  • 1 1/2 tablespoons sugar
  • 1 teaspoon salt
  • 3/4 cup + 2 tablespoons butter-flavored shortening
  • 1/2 egg, beaten

For the pie

  • 3 eggs
  • 1 and 1/2 cups granulated sugar
  • 2 tablespoons instant tapioca
  • 1/4 teaspoon salt
  • 1/4 cup flour, spooned and leveled
  • fresh nutmeg, grated (up to 1/4 teaspoon)
  • 4 to 5 cups rhubarb, sliced and chopped 1/2 inch thick
  • 2 tablespoons cold butter, cut into pieces


    For the crust:

    1. Measure out 1/4 cup water into a glass measuring cup and stick it in the freezer.
    2. In a large bowl, whisk together flour, sugar, and salt.
    3. Use a pastry cutter or fork to cut in the shortening. Cut until it looks like coarse crumbs. Don't overdo it!
    4. In a small bowl beat one egg. Pour out half (into the sink or into another container, or heck, into a frying pan). You can just eyeball it.
    5. Add the half beaten egg to the cold water that you put in the freezer. Beat it together, then add it to the shortening mixture. Stir until it is just coming together, then use your hands to knead it once or twice (only to make it come together). Divide the dough in half.
    6. Generously sprinkle flour onto a sheet of parchment paper. Roll the dough with a rolling pin, using as much flour as you need so that it doesn't stick. Invert the parchment paper onto a 9-inch pie pan and gently peel off the paper. Arrange the pie crust and trim edges as necessary.
    7. Repeat with the remaining dough, up until the invert step.

    For the pie:

    1. Preheat the oven to 400 F.
    2. In a stand mixer or large bowl, beat eggs on medium speed for about 2 or 3 minutes, until they are a light lemon color.
    3. Add the sugar and beat on medium for one more minute.
    4. Add 2 tablespoons of instant tapioca and combine thoroughly.
    5. Add the salt, flour, and nutmeg, and beat well.
    6. Stir in the rhubarb with a rubber spatula.
    7. Pour into the prepared pie crust. Mound the rhubarb slightly in the middle. Sprinkle the cut butter evenly over the mixture.
    8. Transfer (invert) the top crust over the pie and seal the edges.
    9. Cover the edges of the crust with a pie crust cover or foil (see note).
    10. Bake in the preheated oven for 40 to 45 minutes, until the crust is golden.
    11. Remove from the oven and let stand until room temperature, several hours. You can speed things up by putting it in the fridge if you want.
    12. Store covered on the counter. Warning: this means you will take bites of it every time you pass through your kitchen. Sorry in advance.

    Then flatten that puppy out. I like to use parchment paper so that I don’t have to worry so much about the transfer. Just peel it right off.

    Left is what your eggs should look like after beating the eggs. Right is what it turns into after the flour step.

    Rhubarb Custard PieDon’t forget the tapioca! It’s a great thickener. I used good ol Kraft.
