I am hosting a speaker on Cuban cuisine, according to Jose Arrom, "According the authoritative Cuban cookbook by Nitza Villapol, there is Congri (congris) or Congo rice; from eastern Cuba, made with red kidney beans, and cooking with bacon chunks, and even pork shoulder chunks.
"And, Moros y Cristianos (Christians and Moors), from western Cuba, made with Black beans, cooked with pork rind or ham and even white pork pieces."
I didn't know anything beyond black beans until this as well.
