This is from the NY Times site. Is he one of those who won't share a recipe?

2 1/4 cups cake flour
1/2 teaspoon baking soda
1 teaspoon salt
2 cups cold water

Well sort of, Ginger. He said that his son got it from a Japanese family who had used it for generations and asked him to keep it a secret. LOL. The man is a bit elderly and the Internet is like a foreign language to him, so I just didn't press.

Thanks so much for the recipe. I had searched for it and couldn't find it.

Oh, I understand. Hope this is like his.
