01 - Preheat the oven to 350°F (175°C).
02 - Combine all-purpose flour, almond flour, and salt in a mixing bowl. Add solid coconut oil and mix until crumbly. Drizzle in maple syrup and cold water, mixing until the dough comes together.
03 - Press the dough evenly into 6 mini tart pans or one 9-inch tart pan, pressing up the sides. Prick the bases with a fork to prevent bubbling.
04 - Bake tart shells for 15-18 minutes until lightly golden. Set aside to cool completely before filling.
05 - Combine raspberries and sugar in a small saucepan over medium heat. Cook, stirring constantly, until raspberries break down completely, about 5 minutes.
06 - Pour the mixture through a fine mesh sieve to remove seeds, pressing firmly with a spatula to extract as much liquid as possible.
07 - Return the raspberry puree to the saucepan. Whisk in coconut cream, lemon juice, cornstarch, vanilla, and turmeric if using.
08 - Cook over medium heat, whisking constantly, until the mixture thickens and bubbles, about 4-5 minutes. Remove from heat immediately.
09 - Pour the curd into the cooled tart shells. Smooth the tops with a spatula and refrigerate for at least 2 hours or until completely set.
10 - Top with fresh raspberries, mint leaves, and a dusting of powdered sugar if desired. Serve chilled.
