What's In Your Corned Beef?

For St. Patrick's Day tomorrow, I opted to pay $6.99 a pound at Whole Foods for the corned beef they cure in-store that contains nothing but the following: beef brisket, corned beef seasoning (sea salt, garlic, clove, paprika, soybean oil), and pickling spice (black pepper, mustard seed, red pepper, allspice, dill, bay, cloves). You can find other corned beef for considerably less in at least two of our "natural" grocery stores in Boulder, but look for this on the label: that it's cured with "sodium phosphates, sodium erythorbate, sodium nitrite." I'm no expert, but I'd rather stick with ingredients I can recognize, like mustard seed.
