I know this isn't really a recipe, but I bought a box of barley tea recently and I want to make it, but all of the directions are in Korean. I know it is really easy. If I just knew how many cups of water to put for each tea bag and how long to simmer it for, that would be great! Also, I know some people make it from scratch with whole barley and they toast it themselves. Is it worth it to make it this way or are the bags good enough? Thanks! You are awesome!
