HLing said, "There's one company that makes a decent tofu that I would eat as is. It has Chinese writings on it, but might be Japanese, or for all I know Californian. There are two letters that means "Tokyo City" , and also "zen taste" (in Chinese characters)They are the only tofu packaged in a rectangular(3.5 in by 7 in?), flat(1 or 1.5 in thick)shape. Aside from the firm and silken, they also have the Fried Firm tofu, which I love to slice and deep fried until crisp, and then dip in chili/garlic/soysauce as snack. In NYC I think Fairway started to carry them and then dropped them. I now can only find them in Japanese markets."
Is the tofu you're referring to the one that comes in an aluminum tub with plastic across the top and light brown the predominant color on the label? I buy that--in the flat shape and size you describe--at Sunrise Mart on St. Marks, either the firm or the Maki (which has grill-like marks), and it is the one brand I eat plain for its good taste and texture. I usually just slice it up and eat without even a dipping sauce or soy, and I find it very satisfying.
I can't read Chinese or Japanese characters, but the label only says what it is in English, the brand is in characters (it's been a while sine I had some, so I don't remember off hand if it is Chinese or Japanese). According to the fine print, it's made in New Jersey.
