Re: ...Can't find epsom salts in Shanghai!! So...

Try to find NIGARI.

Nigari is used in tofu production, it makes protein and fat contained in hot soy milk coagualte into tofu.

Natural nigari is made from Sea Salt , it contains all other salts, of which Magnesium Sulfate is the main ingredient.

Modern tofu producers are actually using "industrial nigari", which is usually clean magnesium sulfate.

Nigari is, I think, Japanese word, but you may try to find what is the name of the substance used in tofu production. Tweet
