Serve it with this Colcannon  potatoes to sop up the gravy.   I love Colcannon potatoes – the cabbage sounds weird but it lends a sweetness to the mix. You can’t quite put your finger on the taste.   It is great way to get some more veggies into your meal.  I don’t think anyone will object to the presence of the cabbage!

This is so simple to make.  You can fix it in the morning and come home to a delicious dinner.

The Colcannon and Brisket both keep and reheat well.

Of course a Guinness would be a perfect accompaniment to this meal.  So get your St. Paddy’s on and go for it! (Since I am not familiar with any Irish wine The Wine Lover will withhold comment and/or judgement here!)

  1. Should this be Guinness Draught (cans with nitrogen widget) or Guinness Stout (bottles) or Extra Stout?

    This is a fantastically tasting brisket recipe. It is the best brisket I have made yet. I highly recommend this. Will be serving it with baked potato. I did have to double the corn starch in the gravy and add more pepper and garlic salt.
