The point of making high meat is for the bacteria on the meat to accumulate. If you cut it fresh there won't be much bacteria. By leaving it in the fridge for a while (average 30 days) it will accumulate plenty of bacteria.
To avoid botulism, you need to use glass, and not plastic. So something like Mason Jars (Ball) are what you'd need. You also need to air it out daily (or at least every 3 days) to avoid bacteria that thrive without oxygen from flourishing. You want bacteria that need oxygen to multiply. To do this, again air it daily. But also make sure you move the meat around so that meat on the edges and bottom of the glass receive oxygen as well.
It usually smells awful, and tastes just as bad. When I first started I had to take it like a pill (put it in my mouth and down it with water). I've gotten used to it since, and recently started swallowing small pieces without water. Eventually I'd like to be able to pull an Aajonous Vonderplanitz lol.
