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 until thoroughly combined and a crumbly dough forms.
03 - Press the dough evenly into the bottoms and sides of the prepared tart pans, creating an even layer. Prick the bases several times with a fork.
04 - Bake for 10 to 12 minutes until lightly golden. Remove from oven and allow to cool completely in the pans.
05 - Whisk together coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt in a saucepan until smooth and no lumps remain.
06 - Place the saucepan over medium heat, whisking constantly, until the mixture thickens and begins to bubble. Continue cooking for 6 to 8 minutes until fully thickened.
07 - Remove from heat and let the lemon filling cool slightly for about 5 minutes. Pour the warm filling into the cooled tart shells, dividing evenly.
08 - Refrigerate the tarts 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.
