Fresh jalapeños stuffed with tuna, mayonnaise, onion and tomato, a classic cold Mexican party snack.

About this recipe

Chiles jalapeños rellenos de atún are one of the most popular snacks in everyday Mexican cooking: fresh jalapeños halved and deseeded to moderate the heat, then stuffed with a mixture of canned tuna, mayonnaise, onion, serrano chilli and tomato. Served cold as a snack or starter, they are a classic at parties and family gatherings. The combination of residual capsaicin from the jalapeño with the creamy tuna filling is addictive.

History & Origin

The jalapeño is probably the world's most famous Mexican chilli and one of the most important crops of the state of Veracruz, from which it takes its name (Jalapa, the state capital). Its use in Mexican cooking dates to pre-Hispanic times, when it was valued both as a condiment and for its medicinal properties. The tradition of stuffing chillies is ancient in Mexico - the 16th-century Florentine Codex already mentions stuffed chillies - but the modern version with canned tuna is clearly a 20th-century creation, emerging with the popularisation of tinned fish in industrial Mexico of the 1940s–50s. Canned tuna became an accessible protein for the Mexican middle and working classes, and its combination with fresh jalapeños became a ubiquitous snack at quinceañeras, popular weddings and family gatherings.

Method

  1. 1

    Wash the jalapeños and cut in half lengthways. Remove the seeds and veins with a small spoon or knife. To reduce the heat, soak the halves in salted water with a splash of vinegar for 15 minutes; then rinse and dry well.

    💡 Wear gloves when handling jalapeños or avoid touching your eyes; capsaicin irritates.

  2. 2

    Drain the canned tuna well. In a bowl, mix the tuna with mayonnaise, finely chopped onion, deseeded tomato and serrano chilli. Add lime juice, coriander and salt to taste. Mix well until you have a uniform filling.

    💡 The filling should be compact, not runny; if there is too much mayonnaise, the filling will slide out of the jalapeño.

  3. 3

    Using a spoon, generously fill each jalapeño half with the tuna mixture, pressing lightly to pack it in well. Arrange on a serving plate.

    💡 You can garnish each jalapeño with an olive, a slice of avocado or a strip of pickled chilli.

  4. 4

    Refrigerate for at least 20 minutes before serving so the flavours meld and the filling sets. Serve cold with crackers or tostadas as a snack.

    💡 Stuffed jalapeños keep refrigerated for up to 24 hours; cover with cling film to prevent them absorbing fridge odours.
