I am brewing a dry stout today and my LHBS store doesn't carry flaked barley. Thinking that it's okay to use minute rice in the occasional light recipe, here's what I did.
I bought a pound of pot barley from the grocery store for 79 cents. I then cooked it up on the stove. A pound of barley, water, bring to a boil and then simmer for about 60 minutes.
I've added it to the mash with the two row and roasted barley. I've had good luck with minute rice (about 6 - 7 points to the pound). Any reason why the pot barley as prepared above won't work? Any thoughts?
