At the Salvadoran Bakery in White Center, you can get loroco shipped from Metapan, a northwestern department of El Salvador.
Loroco (
Fernaldia pandurata) is a plant in the dogbane family with an edible greenish-white flower. It grows in El Salvador and the people there use the flower in soup and as a garnish in other dishes. Most importantly it can be used as a filling in pupusas, the national food of El Salvador, typically in combination with cheese. It is not available year round, so when it comes 'round the people want it, apparently here in Seattle too. (
The sign was taken down within a couple weeks).
Loroco is also an alternative way to say 'loco' in El Salvador, so "sos loroco" means "you're crazy."
