Storage: This dish is best served chilled. Store leftovers in an airtight container in the refrigerator for up to 2 days.
Substitutions: If whole trout is unavailable, you can use trout fillets, but adjust frying time accordingly. Fresh lemon juice is essential; bottled juice will not provide the same brightness.
Variations: For a milder version, reduce the number of jalapeños or omit the seeds. You can add chopped parsley if cilantro is not preferred.
