I had family in town this weekend, so I thought I’d kill two birds with one stone by making a killer rhubarb pie to impress my mom and stepdad and also something that’d fit for my year of sheet pans.
Luckily, I came across a rhubarb crostata (if you didn’t know, and I didn’t, it’s basically a free-form pie) recipe from Food and Wine a few weeks ago and ripped out the recipe to make it for their impending visit.
It was the perfect time for a lot of reasons, but mostly because my stepdad loves rhubarb and, frankly, so do the rest of us.
While he’s been the most vocal, I learned from Mom this past weekend that she grew up eating the stalks (home-grown) like they were celery and dipping them into a bowl of sugar. And my stepdad loves another rhubarb pie recipe that my sweetie’s mom made him growing up. And, well, I’m not in the habit of making things I won’t enjoy myself as well.
But another reason it was great is because it was so easy.
Sure, like any pie, it took time, but it was small, bite-size bits of active time followed by plenty of down time to do things like go buy the wine or finally eat lunch after a day of cleaning. It was perfect for being impressive and fitting my schedule.
Oh, and it was amazing.
It probably won’t replace the rhubarb custard that was my sweetie’s childhood recipe, but it is quicker and comes with a creamy topping that makes it a reasonable substitute when we’re in a pinch.
Here’s what I did, sticking close to the recipe:
- 2 c. all-purpose flour
- 1 c. and 2 T. granulated sugar, divided
- 1 t. salt, divided
- 1 ½ sticks butter
- ¼-½ c. ice water
- 2 T. cornstarch
- 2 lbs. fresh or frozen rhubarb, thawed, cut into ½-inch pieces, divided
- 1 T. lemon juice
- ¼ c. chopped candied ginger, chopped (I did a heaping cup because we like ginger too)
- Zest from one orange
- 1 egg, mixed with 1 T. water
- 2 t. demerara sugar
- 1 (8 oz.) container mascarpone
- 2 T. heavy cream
- 3 T. powdered sugar
Make the crust: Combine flour, 2 T. granulated sugar, and ¾ t. salt in a medium bowl. Cut butter into chunks and add into the flour mix using a pastry blender, two knives, or your fingers, until pea-size chunks form. Slowly add the ice water and stir until the mixture starts to come together. Pat into a disk, cover with plastic wrap, and let chill in the refrigerator for at least an hour.
Make the filling: Stir together the remaining 1 c. granulated sugar, the remaining salt, and cornstarch in a medium saucepan. Add in 2 c. of the rhubarb and the lemon juice, and cook over medium heat stirring frequently. Cook until the mixture has thickened and the rhubarb has broken down (it’ll look like a lumpy jam). The recipe says this takes about 12 minutes; I didn’t time it exactly but it felt like nothing was happening and then it was totally thick, so keep a good eye on it.
Meanwhile, place the remainder of the rhubarb into a large bowl. When the cooked rhubarb mixture is done, pour it over the raw rhubarb. Add the chopped ginger and orange zest, and stir until well combined.
Put together the pie: Unwrap the dough, and roll it out on a lightly floured surface to 13-14 inches. Transfer to a parchment-paper lined rimmed sheet pan, and cut into a 12-inch round, discarding scraps. Spoon the rhubarb mixture onto the dough, trying to leave about 2 ½ inches around the border; I did less and it was a really full but it worked. Pleat the edges as necessary and press down to secure.
Finish the pie: Brush the dough with the egg wash and then sprinkle with the demerara sugar.
Refrigerate, uncovered, for about 1 hour until the dough is firm. Meanwhile, heat the oven to 425 degrees.
Bake for 30 to 35 minutes. The recipe says to cool completely before serving but we liked it better the second day where we re-warmed it, so I’d say cool for an hour or 2 and then enjoy with whipped mascarpone!
Whip mascarpone for serving on top: While the pie cooks, or before serving, mix together the mascarpone cheese, the powdered sugar, and heavy cream. Use a hand blender or a whisk to blend for 1 to 2 minutes until fluffy. Serve on top of the warm pie and enjoy!
