01 - Preheat oven to 350°F. Lightly grease 8 mini tart pans or a muffin tin with cooking spray or oil.
02 - In a medium bowl, combine almond flour, melted coconut oil, maple syrup, and salt. Mix thoroughly until a crumbly dough forms that holds together when pressed.
03 - Press the dough evenly into the bottoms and up the sides of the prepared tart pans. Use your fingers or the back of a measuring spoon to create an even layer. Prick the bottoms with a fork to prevent air bubbles.
04 - Bake for 10 to 12 minutes until lightly golden around the edges. Remove from oven and set aside to cool completely while preparing the filling.
05 - In a medium saucepan, whisk together coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt until smooth and no cornstarch lumps remain.
06 - Place the saucepan over medium heat, whisking constantly to prevent scorching. Bring to a gentle bubble and continue cooking for 6 to 8 minutes until the mixture thickens considerably and coats the back of a spoon.
07 - Remove from heat and let the filling cool for about 10 minutes, stirring occasionally to prevent a skin from forming. Pour the warm custard into the cooled tart shells, dividing evenly.
08 - Refrigerate the tarts for at least 1 hour, or until the filling is completely set and firm to the touch. For best results, chill 2 to 3 hours before serving.
09 - Top with fresh berries, thinly sliced lemon zest curls, or edible flowers just before serving. Serve chilled or at slightly cool temperature.
