Kaitlyn de Lima Recipe: Creamy Peruvian Lime Dessert

Kaitlyn de Lima is a creamy, citrusy Peruvian dessert that combines sweetened condensed milk, fresh lime juice, and a touch of vanilla, thickened with cornstarch and chilled until set. Itâ€™s a no-bake treat that delivers a bright, tangy flavor balanced by rich sweetness, making it a refreshing ending to any meal. This version is simple to prepare with everyday ingredients and sets beautifully in the refrigerator.

Ingredients

1 can (14 oz / 396 g) sweetened condensed milk
1 cup (240 ml) whole milk
1/2 cup (120 ml) fresh lime juice (about 4-5 limes)
1 tablespoon (8 g) cornstarch
1 teaspoon vanilla extract
Zest of 1 lime (optional, for garnish)
Fresh mint leaves (optional, for garnish)

Instructions

In a small bowl, whisk the cornstarch with 2 tablespoons of the whole milk until smooth and free of lumps. Set aside.
In a medium saucepan, combine the sweetened condensed milk, remaining whole milk, and lime zest (if using). Place over medium heat and stir constantly with a whisk until the mixture is hot and steaming, about 3-4 minutes. Do not let it boil.
Reduce the heat to low and slowly pour in the cornstarch mixture while whisking continuously. Continue to cook, whisking often, until the mixture thickens to a thin custard consistency that coats the back of a spoon, about 5-6 minutes. It should be smooth and slightly thickened, not overly thick.
Remove from heat and stir in the vanilla extract. Let the mixture cool for 5 minutes, then gradually whisk in the fresh lime juice. The mixture will thicken slightly as the acid reacts with the milk.
Pour the mixture through a fine-mesh strainer into a large liquid measuring cup or bowl to remove any lumps or zest (if you didnâ€™t want zest in the final texture).
Divide the mixture evenly among 6 small dessert glasses or ramekins (about 1/2 cup / 120 ml each). Cover each with plastic wrap, pressing it directly onto the surface to prevent a skin from forming.
Refrigerate for at least 4 hours, or until fully chilled and set. The dessert should be firm enough to hold its shape when spooned, but still creamy.
Before serving, garnish with a little lime zest and fresh mint leaves, if desired.

Tips

Fresh lime juice is essential: Bottled lime juice often has a flat, bitter taste. Roll the limes on the counter before juicing to get more juice. Strain the juice to remove pulp if you prefer a smoother texture.
Donâ€™t over-thicken: The mixture will thicken more as it chills. If you cook it too long, the dessert can become too stiff and pudding-like. Aim for a consistency slightly thinner than a traditional pudding before chilling.
Make it ahead: This dessert is perfect for preparing a day in advance. It keeps well in the refrigerator for up to 3 days, making it great for parties.
Substitution: If you donâ€™t have cornstarch, you can use an equal amount of arrowroot powder. The texture will be very similar, though arrowroot can become slightly more gelatinous if over-stirred.

Serving Suggestions

Serve kaitlyn de lima chilled in small glasses or ramekins. It pairs beautifully with a crisp butter cookie or a light biscotti on the side. For a festive touch, top with a dollop of lightly sweetened whipped cream and a thin lime slice. Itâ€™s also lovely as a palate cleanser after a spicy meal, or as a light dessert after a heavy dinner.

Variations

Key Lime Version: Replace the regular lime juice with key lime juice for a more aromatic, slightly tarter flavor. You may need to adjust the sweetness with a tablespoon of sugar.
Lemon Kaitlyn: Swap the lime juice for fresh lemon juice to make a lemon version. Add a teaspoon of lemon zest to the milk mixture for extra brightness.
Mango Swirl: Before chilling, swirl in 1/4 cup (60 ml) of mango puree into each glass for a fruity twist.
Vegan Option: Use full-fat coconut milk (about 1 1/2 cups / 360 ml) instead of whole milk, and use a vegan sweetened condensed milk (or make your own with coconut milk and sugar). The texture will be slightly richer and more tropical.

Storage and Reheating

Store any leftover kaitlyn de lima in the refrigerator, covered, for up to 3 days. Do not freeze, as the texture will become watery and grainy upon thawing. This dessert is served cold, so there is no need to reheat. If it has been refrigerated for more than a day, give it a gentle stir before serving if it has separated slightly (this is normal).

Frequently Asked Questions

Can I use bottled lime juice? Itâ€™s not recommended. Fresh lime juice provides a bright, clean flavor that bottled juice lacks. Bottled juice often has a bitter aftertaste and can make the dessert taste flat.

Why did my mixture curdle? Curdling can happen if the milk gets too hot or if the lime juice is added too quickly. Always keep the heat low and add the lime juice gradually while whisking constantly. Also, make sure the mixture has cooled slightly before adding the juice.

Can I make this without cornstarch? Yes, you can use gelatin as a thickener. Sprinkle 1 teaspoon of unflavored gelatin over 2 tablespoons of cold water, let it bloom for 5 minutes, then heat it gently until dissolved and whisk it into the warm milk mixture. The texture will be more like a panna cotta.

How do I know when itâ€™s set? After 4 hours, gently jiggle the glass. The surface should be firm and not wobble like a liquid. If it still ripples, refrigerate for another 30-60 minutes.

Can I use limes that are not fresh? Fresh limes are best, but if you must use bottled, choose a high-quality brand without added sugar or preservatives. The flavor will still be less vibrant.

Is this dessert very sweet? It is sweet, but the lime juice cuts through the sweetness significantly. If you prefer a less sweet version, reduce the condensed milk by 2 tablespoons and add 2 tablespoons of extra milk to compensate.
