One reason fudge gets grainy is because it is rushed... When heating the sugar, butter and milk start on low heat (I use simmer setting) for about 12-15 minutes until sugar is throughly dissolved (put small amount on spoon, raise out of pan, let cool a couple of seconds and rub some between your thumb and forefinger, if you feel sugar it's not dissolved yet, keep stirring), once dissolved then raise heat to med-hi to bring to a boil. If you don't rush it you will not regret it. This is true with any flavor fudge!
