Scurvy grass - preparation and kitchen utensils
I would suggest that you look to Rene Redzepi's new Nordic cuisine, which sources the very type of ingredient(s) in which you're interested. Common scurvy-grass grows along French, northern Spanish, Danish and Norwegian coasts and on mountain peaks in Western Europe. Weigh anchor and sail to the Basque Country coast, and search the Barbadun, Plentzia and Urdaibai estuaries.
