Okay. Yeah. Whaaaaaat? So to begin, soy sauce is made from fermented paste composed of mashed soy beans, roasted wheat, brine, and Aspergillus mold. Dehydrated soy sauce is that liquid boiled down until only solids remain. These solids are then lightly toasted and milled into a fine, sand-colored powder. Liquid soy sauce can be made with this powder by mixing one-part dehydrated soy sauce powder to one and a half parts water. Makes it easy for when you want to take soy sauce with you on a vacation or camping trip, but don’t want to carry a heavy bottle of liquid. Other uses include adding to dry meat rubs and mixtures or homemade pasta dough.
