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 - Combine almond flour, melted coconut oil, maple syrup, and salt in a mixing bowl. Mix thoroughly until a crumbly, cohesive dough forms.
03 - Press the dough evenly into the bottoms and up the sides of each tart pan. Use your fingers or the back of a measuring spoon to create uniform thickness. Prick the bases several times with a fork.
04 - Bake for 10-12 minutes until lightly golden around the edges. Remove from oven and allow to cool completely in the pans.
05 - While crusts cool, 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 saucepan over medium heat, whisking constantly. Continue cooking for 6-8 minutes until mixture thickens noticeably and begins to bubble. Do not boil.
07 - Remove filling from heat and let cool for 5-10 minutes. Pour the warm custard into the cooled tart shells, filling each nearly to the top.
08 - Refrigerate tarts for at least 1 hour until filling is completely set and firm to the touch.
09 - Top with fresh berries, thinly sliced lemon zest, or edible flowers just before serving. Serve chilled.
