Regarding Japanese seasonings, I have some favorites such as; wasabi, kombu dashi and mayonnaise. My kind of vegetarian diet does not consume alcohol, so even though there is a wonderful Japanese seasoning, mirin, I am not able to use it in my cooking.
Recently, I had the opportunity to travel to Tokyo, Japan and stay for more than 30 days. During this period, I needed to figure out how to survive as a vegetarian and not consume any spices or ingredients from the onion or garlic families.
