In a small saucepan over medium heat, add the lemon juice, milk, sugar, and starch, as well as the lemon zest and turmeric (if using).
Whisk everything until smoothly combined, and continue whisking until the mixture begins to thicken, about 5 minutes.
Once the curd has visibly thickened and is the texture of a creamy curd, turn off the heat, and then add the vegan butter, mixing until fully melted and well incorporated.
Serve the curd right away or keep it stored in an airtight container in the refrigerator for up to one week.
Enjoy!

Notes
Sugar: Any granulated sugar can be used, but white sugar will result in that classic yellow color, whereas coconut or brown sugar will result in a much darker curd.Whisk Constantly: To prevent lumps and ensure a smooth texture, keep whisking the mixture as it cooks.Adjust the Thickness: If your curd is too thick, you can thin it out by whisking in a little more plant-based milk. If it's too runny, cook it for a few minutes longer.Balance Sweet and Tart: Adjust the amount of sugar and lemon juice to strike the perfect balance between sweetness and tartness according to your taste.Use Fresh Ingredients: Fresh lemon juice and zest make a significant difference in flavor. Whenever possible, opt for fresh lemons.Experiment with Citrus: You can try this recipe with other citrus fruits like lime, orange, or grapefruit for a different flavor profile.Add Aromatic Herbs: Infuse the curd with herbs like thyme or basil for a unique twist.
