Strawberry-Rhubarb Vanilla Cream Pie with Ginger-Oatmeal Crust

strawberry rhubarb

This is one of the first recipes that I can actually call my own and I’m darn proud of it! It’s so much easier to spontaneously throw together dinner or lunch without a recipe, not so much with baking. I was inspired by the rhubarb sundae at Earth to Table Bread Bar and it was the perfect dessert for a spring potluck. Sadly, the occasion was a going-away party for some of my parent’s closest friends that are retiring to island life in British Columbia. The entire night everyone reminisced and told crazy stories while passing salad bowls, mixing rhubarb cocktails, and feasting on dishes made with love.

I started with the essential spring vegetable/fruit rhubarb, correctly categorized as a “herbaceous perennial”, more usefully categorized as “confusing red celery plant that gets put into desserts instead of salads”. My mother loves rhubarb and we’ve been poaching harvesting from our neighbour’s garden since we moved into the neighbourhood. If you ever saw two Asian women in the rain waving large chef knives in the garden, it was definitely my Mom and I. Plenty of cars passed by and slowed down as we hacked away at the crimson stalks, safari style.

Rhubarb is quite tart and most people add cups of sugar to balance that fresh pucker-inducing flavour. Sometimes people go too far and make it sickly sweet – what’s the point of even using rhubarb if you’re drowning it in sugar? Rhubarb is quintessential spring – it should taste fresh above all else. Adding strawberries to sweeten is much more appealing, in my opinion.

Not everyone likes rhubarb though – it’s definitely an acquired taste. After years of rhubarb pies and compote I’m a fan for life, but just in case I decided to make a Strawberries + Cream version of the pie as well. It worked out deliciously with the rich vanilla pastry cream and the thick, nutty oatmeal crust. You could even use the oatmeal + fruit combo as an excuse to eat it for breakfast.

Strawberry-Rhubarb Vanilla Cream Pie with Ginger-Oatmeal Crust
(adapted from Serious Eats, Dorie Greenspan, and Chocolate & Zucchini)

Bake the crust and make the pastry cream first because both components need to chill. While they’re in the fridge you can prepare the fruit. The pastry cream is finicky part of this recipe, everything else is easy! Feel free to add more crystallized ginger, you need quite a bit of it before the taste actually comes out.

INGREDIENTS
For the Crust
2 cups rolled oats
1 cup all-purpose flour
2 teaspoons cinnamon
2 to 3 tbsp finely chopped crystallized ginger
1/4 cup dark brown sugar
1 teaspoon vanilla
1 cup butter (melted)

For the Pastry Cream
2 cups whole milk
6 large egg yolks
1/2 cup sugar
1/3 cup cornstarch, sifted
1 + 1/2 tsp pure vanilla extract
3 + 1/2 tablespoons unsalted butter, cut into bits at room temp

For the Topping
1 large box (~1 lb) of ripe strawberries, washed, hulled, and sliced
1 kg (2.5 pounds) fresh rhubarb stalks
2/3 cup unrefined cane sugar (1 cup for a sweeter tooth)
10-cm (4-inch) segment of a plump vanilla bean, or 2 teaspoons natural vanilla extract

INSTRUCTIONS
For the Crust

  • Mix oats, flour, cinnamon, crystallized ginger, sugar, and vanilla together in a large bowl. Pour melted butter over mixture and stir until completely combined. Press mixture into bottom and sides of pie plate (makes either one very thick crust or two normal crusts) and refrigerate until ready to use.

For the Pastry Cream

  • Bring milk to boil in small saucepan.
  • Meanwhile, in a heavy saucepan, whisk the yolks together with the sugar and cornstarch until thick and well blended. Still whisking, drizzle in about 1/4 cup of the hot milk – this will temper (or warm) the yolks so they won’t curdle. Continue whisking and slowly add the rest of the hot milk.

Put the pan over medium heat and whisk vigorously, bringing the mixture to a boil. Boil for two minutes whisking continuously and remove the pan from the heat.
  • Whisk in the vanilla extract. Let sit for 5 minutes, then whisk in bits of the butter, stirring until it is fully incorporated and the pastry cream is smooth and silky. Scrape the cream into a bowl and create an airtight seal with plastic wrap and refrigerate until cold. If you want it to cool quickly, put the bowl into a larger bowl filled with ice cubes and cold water, and stir the cream occasionally until it is thoroughly chilled, about 20 minutes.

For the Poached Rhubarb

  • Trim both ends of the rhubarb stalks. Cut the stalks in 1-cm (1/3-inch) slices, unless they are pencil-thin, in which case you should cut them in 2.5-cm (1-inch) segments.
  • Put the sugar and 500 ml (1/2 quart) fresh water in a medium saucepan. Split the vanilla bean lengthwise with a sharp knife, scrape the seeds from the inside of the bean with the dull side of the blade, and add them and the bean to the pan. Bring to a simmer, stirring regularly as the sugar dissolves.
  • Add a quarter of the rhubarb to the simmering syrup — resist the temptation to add more, the rhubarb won’t cook evenly if the pan is crowded — cover, and allow the mixture to return to simmering point. Once the syrup simmers, cook for just 1 minute, until the rhubarb pieces are soft (test with the tip of the knife, it should meet minimal resistance) but still holding their shape.
  • Remove the rhubarb with a slotted spoon, leaving the syrup in the pan, and transfer to a serving dish or container.
  • Repeat with the rest of the rhubarb, one small batch at a time. Add the syrup and the vanilla bean to the dish.

Assemble the Pie

  • Remove pastry cream from refrigerator and mix until smooth
  • Take chilled pie crust(s) and fill with pastry cream
  • Top with sliced strawberries and poached rhubarb, chill or serve immediately.
