We use Sauce (which is a brown sweet / salty sauce of ketchupy consistency),
Nori (powdered
seaweed), Katsuobushi (shaved
flakes of dried Bonito fish), and a criss - cross of mayonnaise.
You can buy kelp or dulse
flakes to sprinkle on food, add dried kombu to soups and stews, add a side of
seaweed salad when you're at the sushi restaurant, and use
nori wraps as an alternative to bread or grain - based wraps.
