Brisket sauce

Smoked my first brisket yesterday and it came out great. While I thought it was just delicious on it's own (used the wet brown sugar rub from this site), several of my guests suggested that a dipping or side sauce would have been great as well. One suggested a horse radish based sauce perhaps. Any ideas from you expects out there? I have a lot of leftovers and plan on serving them tomorrow, perhaps with a new side sauce.

TH, Welcome!!

Here are 2 that are horsey based and very good on beef.

HORSERADISH DIPPING SAUCE
