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 that holds together when pressed.
03 - Press dough evenly into the bottoms and sides of the prepared tart pans, creating an even layer. Prick the bases several times with a fork to prevent bubbling.
04 - Bake for 10-12 minutes until lightly golden around edges. Remove from oven and let cool completely in pans.
05 - While crusts bake, whisk coconut milk, lemon juice, lemon zest, maple syrup, cornstarch, turmeric, and salt in a medium saucepan until cornstarch is fully dissolved and mixture is smooth.
06 - Place saucepan over medium heat, whisking constantly to prevent scorching. Continue cooking until mixture thickens considerably and begins to bubble, about 6-8 minutes.
07 - Remove filling from heat and let cool for 5 minutes. Pour warm filling into cooled tart shells, dividing evenly among all tarts.
08 - Refrigerate tarts for at least 1 hour until filling is completely set and firm to the touch.
09 - Top tarts with fresh berries, thinly sliced lemon zest, or edible flowers just before serving, if desired.
