fleur de sel?

it’s a hand harvest kind of sea salt.

the wikipedia entry is wrong.

it’s called “flower of salt” because in the season where conditions are right for collecting the salt, violets bloom on the shores of the area it originally was harvested, which gave it a slight purple tinge, and slight taste of flowers.

another part missing from wikipedia is the “paludiers” (the salt gatherers) we’re traditionally women, because the work required patience and finesse, and the coastal French culture associated these traits as stronger in women.
