Final answer:
The 'avocado wall' in ceviche blanco is likely a creative presentation technique involving avocado in the dish, indicating a fusion of flavor and visual appeal, and possibly referencing a unique twist from Hurtado's poem.
Step-by-step explanation:
In the context of ceviche blanco, the 'avocado wall' seems to refer to an innovative culinary technique or presentation style in which slices of avocado are used to create a barrier or decorative element in the dish. As avocados are a standard component of guacamole, known for its combination of avocados, lemon juice, onion, tomatoes, coriander, and seasoning, the mention of Hurtado's poem suggests a creative twist on this traditional mix, perhaps altering the presentation or ingredients in a novel way that is unique to the ceviche blanco. While the specific use of the avocado wall in ceviche blanco isn't detailed, it implies the use of avocados not just for flavor but also as an integral part of the dish's visual appeal or structure, which could potentially influence the texture and experience of the dish.
