I don't know how this might translate to you all not in Australia, but I have an amazing slow cooker recipe for corned beef/silverside.

It's 1.5 Kilo (mine was 1.7 kilo) of lean corned silverside.
2 tablespoons brown sugar
1 tablespoon Balsamic Vinegar
2 fresh mint sprigs
1 onion, peeled and studded with 4 cloves
1 carrot, peeled and cut up roughly into chunks
2 cups/500 ml water
6 peppercorns

So you put it all in the cooker on low for 10-12 hours. (or High setting for 6-7hrs)

I made a white onion sauce to go with it and steamed carrots, potatoes and beans.

YUM. The most tender silverside I've ever tasted
