01 - Combine diced mangoes and lemon juice in a blender or food processor. Blend until completely smooth, ensuring no fibrous pieces remain.
02 - In a medium saucepan, whisk together the sugar and cornstarch until evenly distributed and no clumps are visible.
03 - Pour the mango purée and coconut milk into the saucepan with the sugar mixture. Whisk thoroughly until the cornstarch is fully dissolved and the mixture is uniform.
04 - Set the saucepan over medium heat. Cook while whisking continuously until the mixture begins to bubble and thicken noticeably, approximately 5–8 minutes. The curd should coat the back of a spoon.
05 - Remove the saucepan from heat immediately upon thickening. Stir in the vanilla extract and turmeric for color enhancement.
06 - Transfer the curd to a clean jar or bowl. Allow to reach room temperature, then refrigerate for at least 2 hours to achieve proper consistency.
07 - Serve chilled as a spread on toast, swirled into yogurt, or as a layer in desserts.
