Key Lime Curd: The Perfect Filling, Topping & Spread
Citrus curd is such a wonderful condiment. I remember eating curd with beignets at one of my favorite restaurants during college, and of course it’s a staple at afternoon tea. Honestly, I didn’t even realize traditional curd was made with eggs, but I knew I loved it and wanted to create a plant-based version for the blog. Since key lime is one of my favorite flavors, a Key Lime Curd felt like the perfect place to start. Using bottled key lime juice keeps things simple, and the result is bright, tangy, and incredibly versatile. Try it in a yogurt parfait, dip beignets into it, spread it on scones, swirl it into muffins, or use it between layers of cake.

Ingredient Highlight: Key Lime Juice
Key limes are smaller and more aromatic than traditional Persian limes, with a tart, slightly floral flavor that makes them perfect for desserts. They are most commonly associated with Key Lime Pie, but their bright citrus flavor works beautifully in curds, bars, cakes, and sauces. Fresh key lime juice is wonderful if you can find it, but bottled options like Nellie & Joe’s are widely used and work great here. It’s the ingredient that gives this curd its signature tangy flavor.
Madly Delicious Must-Know Tips & Questions

Can I use regular lime juice?
Yes. The flavor will be slightly different, but regular lime juice works well if key lime juice isn’t available.
How should I use key lime curd?

Let’s Dish: Did You Know?
Despite their name, key limes didn’t actually originate in the Florida Keys. They were brought to the Caribbean and Florida by Spanish explorers centuries ago and became widely cultivated throughout the region. Key lime pie became popular in the Florida Keys in the late 1800s and helped make key limes famous across the United States. Because key limes are smaller and contain more seeds than regular limes, bottled key lime juice has become a popular shortcut for many bakers and home cooks.
