Tips and Variations
Here are a few tips and tricks!
Mustard – The stone ground mustard can be replaced with Dijon mustard or brown mustard. I do not recommend using plain yellow mustard.
Beer – I like to use a lighter beer for roasting, but you can use any beer that you love. Try using a stout such as Guinness for St. Patrick’s Day dinner.
Additions – If you prefer a bit of sweetness to your corned beef, add 2 Tablespoons of dark brown sugar to the mustard.

Haven’t made yet. Is there an alternative to the beer?
Hi Winn. I would try gingerale or even beef broth.
I haven’t made this yet because I’m wondering if I could add the standard corned beef veggies to the pan with the meat?
Hi Susie. Yes, you can add the veggies to the pan, but you will not want to leave them in for the full 3 1/2 hours. Depending on what you are adding, I would recommend adding potatoes and carrots with about 1 1/2 hours left and cabbage at 1 hour or less left.
