We paired our Gluten-Free Crust with Zsu Dever‘s Lemon Custard and Aquafaba Meringue for a perfect pie. It’s amazing! This is REAL meringue without using egg whites.
We highly recommend getting her Aquafaba cookbook for all the details about making Aquafaba meringue and a lot more. We made our Aquafaba from cooking chickpeas in water and then reducing the remaining bean water to a thick liquid. The Aquafaba cookbook goes into detail on how to do this. Listen to the interview with Zsu Dever to get more tips with Aquafaba.
1 1/3 cups water, divided
1/4 cup arrowroot or cornstarch
1 teaspoon agar powder
1 cup fresh lemon juice
1/3 cup raw cashew pieces, soaked overnight
1 1/4 cups granulated organic sugar
1 Tablespoon nondairy butter (use soy-free vegan butter to make soy-free)
1 (9-inch) pie crust – Get our easy Gluten-Free Pie Crust Recipe
3/4 teaspoon cream of tartar, divided
1 1/4 cups granulated organic sugar, divided
1/3 cup water
1 teaspoon agar powder
Measure out 1 1/3 cup water ad combine 1/2 cup of it with the arrowroot or cornstarch to form a slurry; set aside. Combine the remaining 5/6 cup water and the agar in a medium saucepan and set aside for 3 minutes to soften. Blend the lemon juice, cashews and turmeric in a blender until very smooth, scraping the sides as needed; set aside.
(The Aquafaba cookbook goes into detail about making sugar syrup) Add the sugar to the agar mixture and bring it to a boil over medium heat, stirring occasionally. Cook the mixture 5 minutes to completely dissolve the agar. Add the lemon mixture and return to a simmer. Add the starch slurry and return to a simmer. gently stir the mixture and cook for 30 seconds. Remove the filling from the heat and stir in the butter. Set the filling aside to mostly cool before adding it to the crust.
Add the aquafaba and 1/2 teaspoon of the cream of tartar to the bowl of a stand mixer. Usuing a whisk, whip the aquafaba for 10 seconds. Using a balloon whip attachment, whip the aquafaba on medium power for 5 minutes. Increase the speed to medium-high and continue to whip for another 5 minutes, or until the aquafaba can
Add the 1/2 cup water and agar to a heavy-bottomed medium saucepan. Set aside to soften for 3 minutes Add the remaining 1/4 teaspoon cream of tartar and the remaining 1 cup sugar tot he middle of the water. Brin the mixture to a boil, stirring constantly to melt the sugar (this will take a few minutes), over medium-heat. Remove the li, wash the sides of the pan with water and attach a candy thermometer; do not sutra again. Cook the syrup until it reaches 260oF (hard-all stage). Turn off the heat and allow the sugar syrup to cook for a few minutes, or until it is no longer bubbling; do not move or jiggle the pan until then.
Once the meringue is ready, slow the machine and add the sugar syrup in a steady stream, trying not to touch the sides of the bowl or the whisk. Once all the syrup has been added, increase the speed to medium-high and while for 4 minutes until the meringue is much cooler.

Spread the meringue on the still-warm filling, spreading it to the edges of the crust to reduce shrinking.
Next we pile it on the Lemon Custard. It was so much fun!
Cool the pie completely overnight before browning the meringue with a pastry torch or under a broil. If using a broiler, turn the pie every 10 seconds until browns, 1 to 2 minutes, to even brown the meringue.
