Product Review (submitted on February 10, 2014):
Got it for Tofu making. Quality and price is pretty good.
The label doesn't tell how much magnesium is contained per g so have to guess how to use. Otherwise quite satisfied.
Note from CFH: Our recipe calls for 1 tsp. of Nigari Flakes to 2 quarts soy milk. http://www.culturesforhealth.com/how-to-make-tofu
