01 - Preheat oven to 350°F. Lightly grease 8 mini tart pans or a muffin tin with cooking spray or a small amount of oil.
02 - In a medium bowl, combine almond flour, melted coconut oil, maple syrup, and salt. Mix thoroughly 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. Use your fingers or the back of a measuring spoon to smooth the edges. 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 - While crusts cool, whisk 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, whisking constantly to prevent scorching. Continue cooking until the mixture thickens noticeably and begins to bubble, about 6 to 8 minutes. The filling should coat the back of a spoon.
07 - Remove the pan from heat and let the lemon filling cool for 5 to 10 minutes, until slightly thickened but still pourable. Carefully pour the filling into the cooled tart shells, dividing evenly among all 8 tarts.
08 - Refrigerate the filled 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 - Top each tart with fresh berries, thin strips of lemon zest, or edible flowers just before serving. Serve chilled and enjoy within 2 days for optimal texture.
