01 - Preheat oven to 350°F. Lightly grease 8 mini tart pans or a muffin tin with cooking spray or a small amount of coconut oil.
02 - In a medium bowl, combine almond flour, melted coconut oil, maple syrup, and salt. Mix with a fork or your fingers until well combined and a crumbly dough forms that holds together when pressed.
03 - Press the dough evenly into the bottoms and sides of the prepared tart pans, creating a thin, even layer. Prick the bases several times with a fork to prevent bubbling during baking.
04 - Bake for 10 to 12 minutes, until lightly golden around the edges. Remove from oven and let cool completely in the pans before filling.
05 - Meanwhile, whisk together coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt in a medium saucepan until completely smooth and no cornstarch lumps remain.
06 - Place the saucepan over medium heat. Whisk constantly until the mixture thickens and begins to bubble gently, about 6 to 8 minutes. The filling should coat the back of a spoon.
07 - Remove from heat and let the lemon filling cool for 5 to 10 minutes, stirring occasionally. Pour the filling into the cooled tart shells, dividing evenly among all 8 pans.
08 - Refrigerate the tarts for at least 1 hour, until the filling is completely set and firm to the touch. For best results, chill for 2 hours before serving.
09 - Carefully remove tarts from the pans. Garnish with fresh berries, thinly sliced lemon zest, or edible flowers before serving, if desired. Serve chilled.
