Artificial Food Coloring Free Cornstarch Lemon Curd
Bright, tangy, and impossibly silky, this lemon curd is the kind of thing you'll want to spoon straight from the jar. Store-bought versions often sneak in artificial dyes or synthetic additives to achieve that picture-perfect yellow color — but this recipe gets its gorgeous golden hue entirely from real lemon juice and zest, no shortcuts needed. Cornstarch steps in as the thickener here, giving the curd a beautifully smooth, glossy texture without any of the fuss of tempering egg yolks. The method is straightforward: whisk everything together, cook until thick and translucent, then finish with cold butter for that rich, velvety finish. Straining the curd at the end ensures a perfectly clean, lump-free result that looks as good as it tastes. Spread it on toast, swirl it into yogurt, or use it as a filling — once you've made it from scratch with ingredients you actually recognize, there's really no going back.

8 servings
- ½ cup fresh lemon juice (from about 3–4 lemons)
- 1 tbsp lemon zest (from about 2 lemons)
- ¾ cup granulated sugar
- 3 tbsp cornstarch
- ¼ tsp fine salt

Whisk together the sugar, cornstarch, and salt in a small saucepan until evenly combined. Add the water and lemon juice and whisk until the cornstarch is fully dissolved with no lumps visible.

Set the saucepan over medium heat and cook, whisking constantly, until the mixture thickens and turns from cloudy to translucent, about 6–8 minutes. Once it begins to bubble, continue whisking for 1 full minute — the curd should be thick enough to coat the back of a spoon and hold a clear line when a finger is drawn through.
