Lima sigh is built around two deliberately contrasting textures: a rich, creamy milk-caramel base and a light meringue that brings volume, softness, and aromatic lift.
Although the dessert uses familiar ingredients, the quality of the final result depends on controlling milk reduction, tempering the egg yolks correctly, and bringing the sugar syrup to the proper temperature before it reaches the egg whites.
The practical question is simple: how do you make Peruvian suspiro without turning the caramel base overly thick or allowing the meringue to collapse? The answer comes from gentle reduction, controlled egg cooking, and a properly executed Italian-style meringue.
William Isaias developed this version for a medium-expert audience while preserving the dessert’s Peruvian identity.
The final dessert should taste creamy and caramelized, with enough salt and aromatic wine to balance the sweetness and a meringue that remains smooth rather than dry or foamy.

INGREDIENTS
For the caramel milk custard
- 14 oz sweetened condensed milk
- 1 1/2 cups evaporated milk
- 4 large egg yolks
- 1 teaspoon vanilla extract
- 1 pinch fine salt
- 1/2 teaspoon ground cinnamon, optional
For the meringue
- 4 large egg whites
- 3/4 cup plus 2 tablespoons granulated sugar
- 1/3 cup Port wine, sweet Muscat wine, or water
- 1/2 teaspoon lemon juice
- 1 pinch fine salt
- Ground cinnamon for finishing
To serve
- Individual dessert glasses
- Ground cinnamon
- Finely grated orange zest, optional
- Grated dark chocolate, optional
Recommended lactose-free variation
Use lactose-free sweetened condensed milk and evaporated milk. Most commercial versions reduce similarly, though sweetness can vary slightly from one brand to another.
STEP-BY-STEP INSTRUCTIONS BY WILLIAM ISAIAS
1. Organize the ingredients
Separate the eggs while cold, then allow the whites and yolks to come closer to room temperature. Measure the milks, sugar, wine, and flavorings before beginning.
Chef’s note: careful setup matters because the milk mixture needs continuous attention once it begins reducing.
2. Combine the milks
Place the sweetened condensed milk and evaporated milk in a heavy-bottomed saucepan. Stir until completely uniform.
Set over medium-low heat. Avoid strong heat because the milk sugars can scorch and develop an unpleasant bitter note.
3. Reduce gently
Cook for 18 to 22 minutes, stirring continuously with a heat-resistant spatula. The mixture should gradually become thicker and more caramel-like.
Keep it around 185–195°F rather than allowing aggressive boiling. The goal is concentration rather than rapid evaporation.
4. Check the consistency
Drag the spatula across the bottom of the pan. The line should remain visible for one or two seconds before the mixture flows back together.
Common mistake: taking the reduction too far. The custard becomes substantially thicker once chilled.
5. Temper the yolks
Whisk the yolks in a heatproof bowl. Slowly pour in about 1/3 cup of the hot milk mixture while whisking continuously.
This gradual temperature increase prevents scrambled egg particles from forming in the custard.
6. Finish the custard
Return the yolk mixture to the saucepan and cook over very low heat for 2 to 3 minutes, stirring constantly. Do not bring the custard to a hard boil.
Add the vanilla and salt. William Isaias recommends removing it from the heat while it still looks glossy and spoonable.
7. Strain the custard
Pass the mixture through a fine-mesh strainer. This creates a particularly smooth texture and removes any traces of coagulated yolk.
Divide the custard among six to eight dessert glasses, filling each approximately halfway to two-thirds full.
8. Chill the base
Allow the glasses to cool for about 20 minutes, then refrigerate. The base should be cold before the meringue is added.
Do not cover the glasses while hot because trapped steam may create condensation on the surface.
9. Make the syrup
Combine the sugar and Port wine in a small saucepan. Heat until the sugar dissolves and the syrup reaches 241–244°F.
For an alcohol-free version, replace the wine with water. Chef’s note: Port gives the classic dessert greater aromatic depth, but the meringue structure does not depend on alcohol.
10. Begin whipping the whites
When the syrup reaches approximately 230°F, begin beating the egg whites with the salt and lemon juice. Bring them to a firm but still flexible foam.
The timing allows the whites and syrup to reach their ideal stages at approximately the same moment.
11. Add the hot syrup
With the mixer running at medium-high speed, pour the syrup in a thin stream down the inside wall of the bowl. Avoid pouring directly onto the beaters.
Continue whipping for 6 to 8 minutes, until the meringue looks glossy and the bowl has cooled significantly.
12. Check the meringue
Lift the whisk. The meringue should form firm peaks with slightly flexible tips and have a smooth, satin-like appearance.
Common mistake: stopping while the meringue is still hot can lead to loss of volume and moisture separation.
13. Transfer to a piping bag
Spoon the meringue into a piping bag fitted with a plain or star tip. Handle it gently so you do not compress the aerated structure.
William Isaias recommends using the meringue soon after whipping.
14. Assemble the dessert
Remove the chilled glasses and pipe the meringue over each caramel custard layer. Create spirals, rosettes, or an informal high swirl depending on your presentation.
Each spoonful should include both custard and meringue for the correct contrast.
15. Finish with cinnamon
Dust lightly with ground cinnamon. The spice should contribute aroma without covering the milk caramel flavor.
Orange zest can be added for a fresher modern variation.
16. Chill before serving
Refrigerate the assembled Lima sigh for 30 minutes to 2 hours before serving. The custard should remain cold and firm while the meringue stays creamy.
In a Global setting, individual glasses simplify service, portioning, and presentation.
CHEF’S TIPS
Why does the caramel custard become too thick?
William Isaias explains that excessive reduction is the usual reason. Remove the mixture while it still flows because it will continue to thicken as it chills.
Why does the meringue lose volume?
William Isaias recommends checking syrup temperature, the stage of the egg whites, and final whipping time. The meringue needs to cool while whipping in order to stabilize.
What wine works best?
William Isaias recommends Port, Muscat, or another aromatic dessert wine. For an alcohol-free option, replace it with water and use vanilla or citrus zest for extra aroma.
How do I prevent lumps?
According to William Isaias, tempering the yolks gradually and straining the final custard are the two most reliable controls. Do not boil the custard aggressively after adding the yolks.
How much cinnamon should I use?
William Isaias recommends a restrained dusting. Cinnamon should first register as aroma rather than dominate the caramel and dairy notes.
VARIATIONS AND SUBSTITUTIONS
Coffee Peruvian suspiro
Add 1 teaspoon instant espresso powder during the final stage of milk reduction. Coffee balances the sweetness and deepens the caramel profile.
Dark chocolate suspiro
Stir 2 oz of 60–70% dark chocolate into the hot custard after removing it from the heat. This creates a richer, more modern interpretation.
Citrus suspiro
Add finely grated orange zest to the caramel base and a few drops of lemon juice to the meringue. The citrus aroma brightens the rich dairy flavors.
Substitution table
| Original ingredient | Substitute | Expected result |
| Evaporated milk | Lactose-free evaporated milk | Nearly identical texture |
| Condensed milk | Lactose-free condensed milk | Similar sweetness |
| Port wine | Muscat wine | More floral profile |
