Oral Allergy Syndrome Friendly Cornstarch Lemon Curd
Bright, tangy, and impossibly silky, this lemon curd delivers serious citrus flavor without any of the raw egg proteins that can trigger oral allergy reactions in sensitive individuals. Traditional lemon curd recipes rely on egg yolks for thickening, which puts them firmly off the table for many people — this version uses cornstarch instead, achieving that same luxurious, spoonable texture through careful stovetop cooking. Fresh lemon juice and zest do all the heavy lifting on flavor, so you're not sacrificing anything in the taste department. The technique is straightforward: whisk, cook until thick and translucent, then finish with cold butter pieces for a glossy, rich result that sets beautifully in the fridge. Straining the finished curd through a fine-mesh sieve gives it that perfectly smooth, professional finish you'd expect from a bakery jar. Spread it on toast, swirl it into yogurt, or use it as a tart filling — it's endlessly versatile and genuinely hard to stop eating by the spoonful.

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.
