How to make a low-carb lemon tart
To make the Keto tart crust:
- Preheat oven to 350 F.
- Combine all ingredients in a bowl and mix with a spatula to combine.
- Press down the bottom and about 1/2-inch up the walls of a 9-inch tart pan. Using a fork, press to make holes on the bottom of the crust.
- Bake at 350 F for 13-15 minutes, until golden.
- Cool completely.
For the Low-Carb lemon curd:
- In a heat proof bowl, combine egg, egg yolks, lemon zest, juice and powdered erythritol.
- Whisk to combine. Fill a large pot with water to create a double boiler.
- Heat over medium heat. Place the heat proof bowl above it. Whisk constantly for 8-9 minutes, until the mixture thickens.
- Strain through a fine mesh strainer and add the butter. Let it cool to room temperature, then cover and refrigerate or fill the tart crust with it.
