Emulsifier Free Cornstarch Lemon Curd
Bright, tangy, and impossibly silky, this lemon curd hits every note you want — sunshine-sharp citrus balanced by sweet butter and a clean, glossy finish. Most store-bought curds and even many homemade recipes rely on egg yolks as the thickening agent, which often come with added emulsifiers or stabilizers depending on the source. Here, cornstarch does all the heavy lifting, creating that luscious, spoonable texture without any of those extras. The method is straightforward: whisk dry ingredients together, cook with lemon juice and water until thick and translucent, then finish with cold butter whisked in piece by piece for richness. Straining the finished curd gives it that perfectly smooth, professional consistency you'd expect from something far more complicated. Spread it on toast, swirl it into yogurt, dollop it onto scones, or eat it straight from the jar — no judgment here. It sets up beautifully in the fridge and keeps things simple with just a handful of clean, recognizable ingredients.

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
- ½ cup water
- 3 tbsp unsalted butter, cut into small pieces
Instructions
- 1
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.
