Tough to take all of it in at once. No worries.
Just for the information.
They say the iodine test isn't really necessary any longer due to the modern highly modified grain. I have a bottle so since I don't plan on putting on a cut like mom did I do the test and it always comes out good.
You simply take a tablespoon or so of the liquid from your mash, let it cool on a white plate (I use a foam disposable bowl) and drip a couple of drops of the iodine in it. If it turns black, it is still starch and did not convert. If it is brown, you are done, it converted to sugars.
