Doing your own curing might seem like too much work, but it's not as difficult as one might think, and it provides the opportunity to adjust the spices for your ideal taste.
Corn originally meant grain, referring to the grains of spice and salt that cover the meat.
What North Americans call corn (off the cob) got that name because individual kernels look like grains.
The use of curing salt (containing salt peter) is essential.
It keeps the meat pink, rather than the brown of over-cooked roast beef, and acts as a preservative to suppress listeria bacteria.
