We happened to source our Koji from a local home chef who maintains their ain living supply.  The thick cuts of meridian sirloin were sourced from our favorite local butcher and then nosotros knew we were working with a product that we were familiar with from a taste perspective.  The Koji nosotros receive was already in a rough pulverisation grade then nosotros but crushed it a fleck further with a pint glass. If purchased in the form of whole grain it would certainly non hurt to requite it a quick manufacturing plant in the Vitamix or similar.

Nosotros placed the sirloins on a one-half-sheet pan with wire rack, generously coated them with the Koji powder, and placed them into the fridge to hang out in open up air for a while.  In our case, we did this for 64 hours merely recommendations autumn into the range of 48-72 hours.  This provides a good buffer to accommodate your cooking process and dining schedule.
