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 until well combined and a crumbly dough forms.
03 - Press the dough evenly into the bottoms and sides of the prepared tart pans. Use the back of a spoon to smooth and compact the crust. Prick the bases with a fork to prevent air bubbles.
04 - Bake for 10–12 minutes until lightly golden around the edges. Remove from oven and let cool completely in the pans before filling.
05 - Meanwhile, whisk coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt in a small saucepan until smooth and no cornstarch lumps remain.
06 - Place the saucepan over medium heat, whisking constantly to prevent scorching. Cook until the mixture thickens and begins to bubble, about 6–8 minutes. The filling should coat the back of a spoon.
07 - Remove the filling from heat and let it cool slightly for about 5 minutes. Pour the warm lemon filling into the cooled tart shells, dividing evenly among the 8 tarts.
08 - Refrigerate the tarts for at least 1 hour, or until the filling is completely set and firm to the touch.
09 - Just before serving, garnish with fresh berries, additional lemon zest strips, or edible flowers if desired. Serve chilled.
