Standard nacho ingredients include tortilla chips, cheese, jalapeños, beans, and meat, with optional additions like olives and guacamole. Sour cream usually is provided either atop the nachos or on the side.
Step-by-step explanation:
The standard ingredients for nachos typically include tortilla chips, cheese, jalapeños, beans, and often ground beef or shredded chicken. Different establishments or recipes might also add olives, guacamole, pico de gallo, and sometimes lettuce. Regarding your specific query about sour cream, it generally comes either on the nachos or on the side, depending on the recipe or customer preference. However, the inclusion of guacamole, as per the traditional recipe, would consist of avocados, lemon juice, onion, tomatoes, coriander (also known as cilantro), salt, and pepper. It's interesting to note that Hurtado's poem seems to add a creative twist to this traditional dish, although the poem's exact ingredients are not detailed in your question.
