An “awesome sauce” can be a very good sauce placed on food. The slang term “awesome sauce” describes someone or something “awesome,” with “sauce” added as an essential ingredient.
 
The slang “awesome sauce” (or “awesome-sauce” or “awesomesauce”) has been cited in print since at least September 2001. The origin is unknown, but the term “awesome sauce” was used in 2001 and in 2003 in the newsgroup for the sketch comedy group The Kids in the Hall.
   
“Awesome sauce is probably the condiment that goes on cool beans” is a joke involving two slang terms.
