This is true single species and closely related to Wild Arugula instead of Roquette Arugula. Compare to another arugulas, this is one of the most piquant and spicy but also has tender succulent texture. Just like the name, it kick you hard in the first bite and gone in few seconds. Lets make it bold, taste exactly like real wasabi and will give you that back-of-the-nose jolt! Also the cute fragile flower is edible and tasty!
They could be a horseradish substitute and better companion for Tuna Tataki, Beef Carpaccio and tartar. They are high in Vitamin A, also contains Vitamin C, Calcium and Iron!
