Mulled Down Shrimp with Hominy Grits

This is real low-country soul food, low-country meaning the coastal areas of the Carolinas and soul food meaning what the black people eat. I like the term mulled down, which expresses well the process of gentle reduction of the gravy, and prefer it to the title Brown shrimp, although that is in common use. ‘Half the black people on this island were raised on brown shrimp and grits,’ I was told on one of the sea islands, the very ones which gave their name to Sea Island cotton long ago.
