Tocino translates to "bacon". While it might seem like a simple food item, its inclusion in a song about a menu, especially in a salsa tune, is quite engaging and unexpected.
In the context of "El Menú," the lyrics list various food combinations, and "arroz con tocino" (rice with bacon) stands out as a delicious and somewhat indulgent pairing. It's a word that evokes comfort food and a specific culinary delight, making it memorable and enticing for someone learning Spanish through music.
