    There are very few sweet treats that can compare to the bright and fresh flavors of key lime desserts. Key lime curd is no exception. And it's so easy to make! If you're are fan of this easy Keto Lemon Curd, you're going to be obsessed with this Key Lime Curd.

    If you've never had curd before, you're probably wondering, " What does Lime Curd taste like?" Lime curd is a smooth and sweet but slightly tart spread-like custard filling. It has more of a citrusy flavor verses the eggy flavor found in most standard custards. Lemon and lime curd is often used in tarts and pastries as a lovely and refreshing filling.

    Growing up in Florida, being able to have fresh key limes was the highlight of many summers. Nowadays, key limes are produced year round in other parts of the world and are available is most of our grocery stores.

    Next time you see them, grab a bag of fresh, ripe key limes and get ready to make one delicious sugar free treat!

    What's in Keto Key Lime Curd

    • Key lime juice
    • Key lime zest
    • Monk fruit/allulose confectioners
    • Butter
    • Eggs
    • Salt

    *Exact measurements are listed in the recipe card below.

    How to Make Key Key Lime Curd

    Heat a saucepan to low and add in the butter.

    Cook on medium-low for 6-8 minutes while whisking the entire time, until thickened enough to coat the back of a spoon.

    Transfer to a bowl and cover with plastic wrap, making sure it's touching the curd. This will help prevent a skin from forming.

    Store in the fridge for up to a week in an airtight jar.

    *Note: if you can't find key limes near you, you can substitute with regular limes and the curd will still turn out perfectly!

    Can I Freeze Lime Curd?

    You sure can. In fact, when frozen in an air tight container this Lime Curd can last up to several months without effecting the taste or quality. That makes it a great make a head recipe for meal prepping desserts in advance.

    What's the Difference in Key Limes and Lime?

    There are several visual differences in limes and key limes. And there is a slight flavor difference. But, honestly, when used recipes with other ingredients, it's very hard to tell the difference in flavor.

    The most notable difference in regular limes or Persian limes and key limes is their appearance. Key limes are more yellow than green when ripe and they contain more seeds than regular limes.

    When you cut into a key lime you will also notice the skin is thinner than regular limes. Because of this, they do not store as long as regular limes, so be sure and use them within a few days of purchasing.

    What are the Carb in Limes? Are Limes Keto?

    In ½ cup, there are approximately 5 net carbs in lime juice. There are 12 servings of lemon curd in this recipe which makes the carb impact very minimal. Not only are limes low in carbs, they are a rich source of vitamin C, antioxidants, and fiber. That makes lime a fantastic flavorful Keto ingredient.

    Wholesome Yum's Besti Powdered Monk Fruit/Allulose is my absolute favorite blend to use! It has perfect texture and far exceeds anything else I've ever tried. Use code: KCC10 to save 10%.

    Tips for Key Lime Measurements and Conversions

    It sometimes can be tricky knowing exactly how many fresh limes you'll need for a particular recipe. Some key limes are larger than others and some even have more juice than others, depending on their level of ripeness.

    Here are a few tips that should act as a general rule of thumb.

    • 1 pound Key limes = 12 to 16 Key limes
    • 1 pound Key limes = ½ to ⅔ cup Key lime juice
    • 1 medium Key lime = 2 to 3 teaspoons Key lime juice

      This is simply a fabulous recipe. It goes in hand in glove with the Keto Keylime Cheesecake recipe. I’ve made it at least six times and every time it turns out perfect and it is a perfect dessert!
