How to Make Lime Curd: Zesty Citrus Spread

Why Lime Curd

If you already love lemon curd, lime curd offers a brighter, more intense citrus note with a slight bitter edge that many cooks prefer. Limes deliver a sharper, more floral acidity than lemons, making lime curd an excellent choice when you want a bold citrus flavor that cuts through sweetness. It’s quick to make—about ten minutes on the stove—and versatile: use it as a spread, a filling, a topping, or folded into creams.

• Limes provide a stronger, more aromatic citrus profile than lemons; choose limes when you want an assertive, tangy finish.
• This recipe is fast and simple; you can use Persian limes, key limes, Tahitian limes, or a mix depending on availability and desired flavor intensity.
• Lime curd works in many applications: spread on toast or scones, as a cake or cupcake filling, swirled into ice cream, or folded into whipped cream for a tangy mousse.

Ingredients

Gather fresh, simple ingredients for the best results.

• Lime juice and lime zest — fresh is best. Zest one lime and juice enough limes to yield about 1/2 cup (120 ml) of juice.
• Granulated sugar — this recipe uses 3/4 cup (150 g), but you can reduce sweetness by up to 1/4 cup (50 g) if you prefer.
• Eggs — one whole large egg plus three large egg yolks. You can substitute two whole eggs or four yolks; room-temperature eggs blend more smoothly.
• Unsalted butter — 1/2 cup (113 g) cut into small pieces and kept at room temperature; adjust the amount to change the curd’s thickness.

How to Make Lime Curd

Follow these clear steps for smooth, glossy lime curd. The full recipe measurements are included in the recipe card below.

1. Zest one lime and rub the zest into the sugar with a fork to release essential oils and scent the sugar.
2. Whisk the whole egg and egg yolks with the sugar and zest mixture, then stir in the lime juice until combined.
3. Pour the mixture into a medium saucepan and cook over medium-low heat, stirring constantly to prevent curdling.
4. Keep stirring until the curd thickens and coats the back of a wooden spoon or rubber spatula—this usually takes a few minutes.
5. Remove from heat and pour the curd through a fine-mesh sieve into a clean bowl to remove any bits of cooked egg or zest.
6. Add the butter a few pieces at a time, stirring until fully incorporated and silky. Cool to room temperature, then refrigerate until chilled and set.

Tips

• Always use fresh lime juice and zest; bottled juice lacks the bright fresh flavor of real limes.
• Cook gently over medium-low heat and stir constantly to prevent the curd from scrambling. If you’re unsure, use a double boiler for gentler, more controlled heating.
• Adjust sugar to taste—limes are tangier than lemons, so this recipe calls for slightly more sugar to balance the tartness.
• For a brighter green color, increase the amount of zest and pulse it with the sugar in a food processor before combining with the eggs.
• Save leftover egg whites to make meringues or pavlovas.
• Use a wooden spoon or silicone spatula; aggressive metal utensils can affect the appearance and texture.

Uses for Lime Curd

Lime curd is a versatile component that adds concentrated citrus flavor to many dishes:

• Spread on toast, scones, or muffins for a bright breakfast or snack.
• Use as a filling for cakes, cupcakes, cookies, tarts, or layered desserts.
• Swirl into yogurt, ice cream, or whipped cream for an instant citrus boost.
• Fold into pastry cream or use to fill choux pastries and cream puffs for a lively contrast to rich dough.

Storage

Store lime curd in an airtight container or jar in the refrigerator for up to five days. Stir briefly before using to restore a smooth consistency. To freeze, place cooled curd in plastic wrap, seal inside a freezer bag, and freeze for up to eight weeks. Thaw in the refrigerator overnight.

Yield

This recipe yields about 1 cup of lime curd. You can double the ingredients to make a larger batch. To halve the recipe, use one whole egg or two yolks accordingly.

• 3 large egg yolks
• 1/2 cup unsalted butter, cut into 1/4 inch pieces (113 g)

Instructions

1. Rub the lime zest into the sugar with a fork to release the oils and fragrance.
2. Whisk the whole egg and yolks with the sugar and zested sugar until smooth. Stir in the lime juice.
3. Pour the mixture into a medium saucepan and cook over medium-low heat, stirring constantly.
4. Cook until the curd thickens and coats the back of a spoon. Do not allow it to boil vigorously.
5. Remove from heat and strain the curd through a fine sieve into a clean bowl to remove any coagulated bits.

Notes

• You can use two whole eggs instead of one egg plus three yolks, or four yolks instead of the whole plus yolks.
