Ingredients
Crust
- 1 ⅔ cup (165g) oat flour (gluten-free if needed)
- ⅓ cup (37g) tapioca flour or cornstarch
- 1 batch flax egg (2 tablespoons flaxseed meal mixed with 4 tablespoons water)
- 3 tablespoons sugar
- ⅓ cup (70g) solid but scoopable refined coconut oil
- 1/4 - 1/2 cup cold water
- Pinch of salt
Filling
- 2 cups full-fat coconut milk (from a can)
- 1 cup soy milk
- 3/4 cup granulated sugar (up to 1 cup for sweeter)
- 8 tablespoons cornstarch
- 1 tsp agar agar powder
- 1/2 cup lemon juice
- Zest of 2 lemons
- ½ tsp turmeric (for color, optional)
- 25 g vegan butter (optional, for richness)
Meringue (optional)
- 1/2 cup aquafaba (liquid from a can of chickpeas)
- 1/2 tsp cream of tartar
- 1 cup powdered sugar
- 1 tbsp cornstarch
Instructions
- Prepare the Crust: In a medium bowl, combine oat flour, tapioca starch, sugar, and salt until well mixed. Add coconut oil, half the cold water, and the prepared flax egg. Mix using your hands until a dough forms, adding more water as needed to achieve a dough that's neither sticky nor dry.
- Roll out the Dough: Place the dough between two pieces of parchment paper and roll it out evenly to about an inch wider than a 9-inch pie dish, ensuring no bumps.
- Transfer to Pie Dish: Remove the top parchment sheet and carefully transfer the rolled dough to the pie dish. Press evenly along the bottom and sides to form the crust.
- Dock and Chill: Use a fork to poke holes all over the crust to prevent puffing. Freeze for 10 minutes while preheating oven to 180°C (356°F).
- Bake the Crust: Bake the crust for 20 minutes until lightly golden. Remove and let cool completely.
- Prepare the Filling: In a medium pot, mix coconut milk, soy milk, sugar, cornstarch, agar agar powder, lemon juice, lemon zest, turmeric, and vegan butter (if using). Stir until cornstarch is fully dissolved.
- Cook the Filling: Heat over medium heat until simmering, then reduce to medium-low and whisk constantly for 5-8 minutes until thickened. Remove from heat, taste, and adjust sweetness or tartness if needed.
- Cool the Filling: Pour the filling into a medium bowl and cover tightly with plastic wrap, ensuring the wrap touches the surface to prevent skin formation. Allow to cool to room temperature.
- Assemble the Pie: Once crust and filling are cool, whisk the filling till smooth and pour into the crust. Smooth with a spatula and refrigerate overnight to set fully.
- Prepare Optional Meringue: Preheat oven to 190°C (375°F) if you don’t have a blow torch. In a stand mixer with a whisk attachment, beat aquafaba on high until foamy.
- Add Meringue Ingredients: Add powdered sugar, vanilla extract, lemon juice, and cream of tartar to the aquafaba. Beat for 5-8 minutes until stiff peaks form.
- Top the Pie: Spoon or pipe the meringue onto the cooled pie. Use a blow torch to brown the peaks or bake in the preheated oven for 5-6 minutes until golden, watching carefully to prevent burning.
Notes
- The flax egg can be substituted with 3 tablespoons of aquafaba for the crust if preferred.
- Use gluten-free oat flour to make the pie gluten-free.
- Turmeric is optional and used just to give the filling a warm yellow color without affecting flavor.
- For best results, chill the pie overnight to allow the filling to fully set.
- The meringue topping is optional but adds a beautiful, light finish.
- If you don't have a blow torch, carefully watch the meringue while baking to avoid burning.
