Simple? Whaddayoulot mean by simple? Guacamole is mashed avacado. Now you need a bit of salt to season. And you need to add some citrus to stop oxidation. But that’s it. Anything else is a fancy Dan variation.
On the citrus a lemon lime mixture (in northern Europe) is closer to the Mexican taste.
Coriander and roasted garlic sheesh! You have a nerve to criticise the pea shenanigans with your fancy Dan variations.
That said I have seen fancy variations in various places in Mexico.
