A silky smooth and tart lemon topping that tastes incredible on biscuits, pancakes, toast, muffins, yogurt, and ice cream. It also makes a fantastic filling in tarts, trifles, and pies.
In a saucepan, whisk together the sugar and cornstarch. Whisk in the milk.
Turn the stove on to medium heat. Whisk in the lemon juice, lemon zest, and turmeric.
Stir occasionally until the lemon curd thickens, about 5-10 minutes.
Turn off the stove, stir in the vegan butter (if using), and allow the curd to cool slightly.
Transfer to a lidded container and store covered in the refrigerator for up to two weeks.
Notes
* I prefer using raw sugar since it retains minerals and nutrients, though it may lend a light natural brown hue to the lemon curd. The turmeric covers this up with a bright yellow hue. I also like using ½ cup sugar, but you can use ¾ cup to 1 cup if you like sweeter lemon curd.** You may substitute arrowroot starch for the cornstarch, if needed.*** The turmeric is optional since it’s used solely for color. You can add just a pinch for a slight yellow hue, ¼ teaspoon for a vibrant sunshine color, or something in between. I used ¼ teaspoon.
