Bright, tangy, and impossibly silky, this lime curd is the kind of condiment that makes everything it touches taste more special. The double hit of fresh zest and juice gives it a bold citrus punch that store-bought versions simply can't match, and the slow double-boiler method ensures a perfectly smooth, luscious texture every time. Eggs and butter are cooked together gently until the mixture reaches a safe temperature, so you get a rich, custardy spread without any guesswork. Straining the finished curd through a fine-mesh sieve removes any stray bits of zest or cooked egg, leaving behind nothing but glossy, velvety perfection. For anyone navigating peanut allergies, this recipe is naturally worry-free — every ingredient is straightforward and easy to source without scanning labels for hidden warnings. Spoon it over yogurt, swirl it into whipped cream, spread it on toast, or use it as a filling for tarts and layer cakes. Once you've made it from scratch, you'll wonder why you ever settled for anything else.

Whisk together the lime zest, lime juice, sugar, whole eggs, egg yolks, and salt in a heatproof bowl until the sugar is mostly dissolved and the mixture is smooth.
Set the bowl over a medium saucepan of barely simmering water, making sure the bottom of the bowl does not touch the water. Cook, whisking constantly, until the curd thickens enough to coat the back of a spoon and a finger drawn through leaves a clean line, and the mixture reaches 170°F (77°C) on an instant-read thermometer, about 10–12 minutes. Reaching 170°F (77°C) ensures the eggs are fully cooked and the curd is food-safe.
