Japan — tofu introduced from China 8th century; Japanese refined technique and developed specific coagulant varieties and textures over centuries · Soy Products
Pure soybean protein with subtle mineral character from nigari — fresh tofu has delicate sweetness that deteriorates within hours of making
Stirring after adding all nigari — breaks the forming gel network; gentle initial stir then absolute stillness Temperature too high — fine-grained, crumbly tofu results from over-rapid coagulation Wrong soy milk concentration — tofu requires full-fat soy milk (not reduced fat versions for drinking)
