Why not make your own corned beef? This recipe is for 12kg of beef but can scaled down. Curing salt, or Prague powder number 1, is a commercial curing product that can be found at sausage supply shops.
very good but use fresh green beans in mine instead of carrots beer instead of water no sugar or vinegar - 15 Feb 2009 (Review from Allrecipes USA and Canada)
I scaled this down considerably to feed 20 people for a party at a friend's house. Even though there was other food there to eat, my dish went fast! People were getting seconds and one guy even took a third helping!!!!! I ut up carrots, potatoes, rutabagas and cabbage to go with it. I left that party with an empty dish! I think that calls for the highest rating I can give it. - 21 Mar 2012 (Review from Allrecipes USA and Canada)
