This specific brand of Alariacalled "Wild Atlantic Wakame" (Alaria esculenta) is biologically and nutritionally similar to Japanese wakame (Undaria pinnatifid). Although it required a slightly longer cooking time it provides a more wild, yet delicate taste which makes it very ideal for miso soup. The mild flavor allows it to complement the other ingredients without overwhelming them.
Powdered Alaria is a great addition to green drinks (try mixing it with kelp and dulse powder) or any energy drink that needs mineral fortification (particularly calcium). It's a great source of vegetable protein, dietary fiber, calcium, iron, potassium, magnesium, phosphorous, vitamins, anti-oxidants, iodine, and other trace minerals.
