Why wouldn’t the cooks of the prehistoric, ash-covered village of Cerén 
in El Salvador have developed sauces to serve over meats and vegetables? 
After all, there is evidence that curry mixtures were in existence 
thousands of years ago in what is now India, and we have to assume that 
Native Americans experimented with all available ingredients. Perhaps 
this mole sauce was served over stewed duck meat, as ducks were one of 
the domesticated meat sources of the Cerén villagers.

Named from ahuacatl "testicle" and mole, meaning “mixture,” this pulpy sauce moved from strictly Mexican use into America around 1900 and slowly increased in popularity as the avocado became more available in American supermarkets.  It really took off after the introduction of corn chips in the 1960s and now is found pre-made in various packages everywhere, but many of them are bland and lack the full flavor of guacamole made from scratch.  This version is traditionally made with a molcajete y mano, a large Mexican mortar and pestle carved from volcanic rock. If you don't have a molcajete y mano, you can smash the avocados with a fork or potato masher. From the article Avocado Madness!

Variations on this hot sauce appear all over Africa, with the key 
ingredient being peanuts in any form. Here, peanut butter works 
well--and it's the cook's choice to use smooth or crunchy! Ladle it over 
fried chicken or fish.
