Edit: I tried it this time using the frozen, salted seaweed. Not sure what kind of seaweed it was. But I just soaked it, then rinsed it, tossed it with vinegar, sesame seeds and sesame oil – and it was better than the rehydrated version.
This makes about 12 small, dense servings of seaweed salad.
1 2 oz pkg of dried hijiki seaweed
1/4 cup rice wine vinegar
2 T ume plum vinegar (could use salt)
1 Tbsp sesame oil
2 tsp sugar
2 Tbsp sesame seeds
sliced cucumber
Soak hijiki in cold water for 30 min-1 hr. Mix remaining ingredients (except cucumber) together in a bowl. Toss with drained hijiki. Pour hijiki salad over cucumber and serve cold.
