A drool-worthy vegan blueberry meringue pie featuring a sky-high meringue atop a luxurious blueberry sauce bursting with flavor! Made with fresh or frozen blueberries, this special treat is sure to impress!
In a small bowl, combine the ground flax, hot water, and maple syrup together. Set aside.
Preheat the oven to 350° F.
In a food processor, pulse the almonds to create a fine almond flour. Add the flax mixture, 4 Tbsp cold water, and salt. Pulse until the mixture is well combined, then add in the flour. Continue to process until a smooth dough forms, adding 1-2 Tbsp more water, if needed. Try not to over-process the dough – it should soft and moist not wet.
Remove the dough and place it on a non-stick mat or lightly floured surface. Use a rolling pin to roll the dough fairly thin. Transfer the dough to your 9 inch tart or pie pan. Press into the sides and remove exceess. Shape and flute the edges, as desired.
Prick the bottom of the crust with a fork and bake for 20-25 minutes, until golden brown. Remove from the oven and set aside.
Meanwhile, make the Blueberry Filling. Stir the cornstarch and water together in a small bowl. Set aside.
Combine the maple syrup, water, and blueberries in a large saucepan over medium to medium-high heat. Bring to a low boil and continue to simmer until the blueberries burst, stirring occasionally, about 10 minutes.
Add the wild blueberries to the saucepan and stir in the cornstarch-water slurry. Bring the blueberries to a simmer and stir occasionally until the sauce thickens slightly, about 5 minutes.
Turn off the heat and stir in the lemon juice and vanilla. Allow the sauce to cool to room temperature.
While the crust and filling are cooling, make the Meringue. In a stand mixer bowl, combine the chilled aquafaba, sugar, and cream of tartar. Mix on medium-high speed until peaks form, about 2-3 minutes.
Continue mixing on medium speed until fully incorporated. Add the vanilla slowly and slowly increase to high speed. Mix 3-5 minutes more, until very stiff peaks form.
Spoon the Blueberry Filling into the cooled crust. Then spread the Meringue atop the Blueberry Filling, leaving wisps and peaks. This pie is ready to serve immediately or use a torch or broiler to toast the Meringue. It takes 3-4 minutes under the broiler. As an option, you can paint blueberry swirls into your merinuge for a striking presentation.
This pie is best enjoyed immediately. Otherwise, the meringue may begin to deflate.
Notes
* I prefer making the almond flour fresh but you can use premade almond flour as well. ** If making this gluten-free, simply substitute with a gluten-free blend like Bob's Red Mill 1:1 Gluten-free Baking Flour.*** Drain aquafaba from canned or home-cooked chickpeas or northern beans and chill in the refrigerator.• The pie crust and blueberry filling can be made in advance and stored in the refrigerator until you are ready to make this pie.
