Put two skillets over medium heat. In the first skillet add a small amount (just enough to cover the bottom). Chop your potatoes and add them to the skillet. If you choose to add any herbs go ahead and do so. Stir these occasionally, but now it is time to move on to the second skillet.

In the second skillet, add the butter and begin melting it. Stir in the flour and mustard powder. Once mixed together add the beer. Stir this together and begin adding the cheese, this is best done in small doses. Keep stirring this, do not let it cool!

Once the potatoes are done, remove them to a plate and put it in the microwave to keep them warm. Then you need to stick your bread in the toaster.

In the first skillet now put in your Corned Beef to heat it up. If you want you can add some beer to the Corned Beef. Let this simmer just for a minute or so.

Once your toast is done get your plates and begin plating. Start with the toast, one on each plate. Then take your Corned Beef out of the skillet and put it on the toast. Follow this up with your potatoes and finish it off with the Welsh Rabbit. And there you have it. A wonderful and filling dish (not for the feint of heart nor those counting their carbs/cholesterol).
