Loroco is small green unopened flower buds used as an herb for flavouring in Central America. The closest taste comparison is might be to chard or spinach, or a cross between mild broccoli and squash. It is used in salads, rice dishes, stews and sauces. In El Salvador and in Honduras, it is added to the fillings in "pupusas." The Loroco plant is a woody vine. It grows wild in El Salvador, Guatemala, Honduras, and Nicaragua, and prefers a temperature range between 68 and 90 F (20 and 32 C.)
Loroco is not available fresh in the United States because the USDA's Commodity and Biological Risk Analysis team discovered that the plants can bring with them the "Diabrotica adelpha" beetle. But loroco can be bought in jars (brined or pickled in vinegar), or frozen. I wonder if the owners of Cabo Hermoso grow it themselves.
