"Tofu (Chinese: 豆腐; pinyin: dòufu; Wade–Giles: tou -fu) is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness: silken, soft, firm, extra firm, or super firm. Tofu is also known as bean curd in English." (Wikipedia)
In the US, tofu is sold as 'soft', 'medium firm', or 'firm' tofu.
