01 - Preheat oven to 350°F. Lightly grease 8 mini tart pans or a muffin tin with cooking spray or oil.
02 - Combine almond flour, melted coconut oil, maple syrup, and salt in a mixing bowl. 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 bubbling.
04 - Bake for 10 to 12 minutes until lightly golden. Remove from oven and let cool completely in the pans before filling.
05 - Whisk together coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt in a saucepan until completely smooth and no lumps remain.
06 - Place the saucepan over medium heat. Whisk constantly until the mixture thickens and begins to bubble, about 6 to 8 minutes. The filling should coat the back of a spoon.
07 - Remove from heat and let the filling cool for 5 to 10 minutes. Pour into the cooled tart shells, dividing evenly among all 8 tarts.
08 - Refrigerate for at least 1 hour until the filling is completely set and firm.
09 - Top with fresh berries, thinly sliced lemon zest, or edible flowers just before serving if desired. Serve chilled.
