Well... I found this on the internet. Surprisingly, it's hard to find a recipe for corned beef from scratch.
Interestingly, some corned beef recipes call for the use of salt peter, which you can get from either the pharmacist or a veterinary supply company. This recipe, as you will see, does not call for that. Whew!
It should be noted that I HAVE NOT tried this recipe yet, but I anticipate doing so for my seder this year. I'll let you know how it turns out.
