Went over to Ireland in 1980 and fished a place called Loch Bran. The locals informed us that if we went to the bran factory at the top of the loch we could buy a sack of it (like conflakes) and use it in the ground bait. We did and bagged up. Since then I've been using Vitalin (its nearest equivalent).
If you fish a water with Bream in, then it will attract them so bare in mind (for quantity) if there is a good head of them because they will devour it.
As Robber has said I have never boiled it the night before I prefer just to use lake water. I do a very wet mix, leave it a couple of minutes then stiffen it with some brown crumb to suit depending on application.
You can literally mix in anything with it depending on your situation. I like putting in pure hemp oil (helps as a binder) or liquid pellet / csl or molasses. I have also used it with success as a method mix. I have often thought about preparing it the night before with boiling water and pellets but to be honest I couldn't be arsed

Give it a whirl its cheap and useful plus it will boost your Bream catches
