Re: Which process?
A process of elimination, obviously. That which might kill you makes more taxes.
Curing is a double whammy which is why bacon is on the list with plutonium. Nitrates are commonly used in making explosives, and whilst there are restrictions on buying nitrates in bulk, there are no such restrictions on bacon. Therefore it is in the interests of public safety to restrict purchases to no more than 6 rashers a month to avoid terrorists creating a very dirty bomb. Imagine the chaos if something with a high bacon load was detonated in an area like Islington.
