Extracted from Charles H. Baker's 'Around the World with Jigger, Beaker & Flask';

"HELL-FIRE BITTERS, another receipt from the Island of Trinidad, in the British West Indies, and now and again used in Gin-and-Bitters & other similar sharp drinks instead of routine bitters by stout Englishmen with boiler plate gastric linings.

This is an old, old reciept dating back to 1817 in print right here before us - and likely before that, because the British knew Port of Spain a century and a half before.

This Hell-Fire Bitters is an excellent cooking and seasoning sauce for fish, salads, soups and meats..."

Alternatively try a few dashes in drinks such as the Mexican Firebush;
