Final answer:
No specific fruit is mentioned as an ingredient in the calavera salad based on the information provided. However, since guacamole's standard ingredients include avocados and tomatoes, which are fruits, these could potentially be considered part of the salad, metaphorically or in a literal culinary sense.
Step-by-step explanation:
The calavera salad mentioned seems to be a reinterpretation of a traditional dish, likely influenced by literature or poetry, rather than a standard culinary recipe.
Given the reference to Hurtado's poem, it's possible that the salad might metaphorically include ingredients that are not typical in a culinary context. Without a direct mention of specific fruit ingredients in the calavera salad from the information provided, it's not possible to state definitively which fruit is included.
Traditional guacamole ingredients do include avocados, which are technically a fruit, and tomatoes, which are also a botanical fruit.
Additionally, the reference to terracotta pomegranates and the cult of Demeter Malophoros suggests a thematic connection to fruit in a historical or symbolic sense, but this does not specifically indicate a physical ingredient in the calavera salad.
