Step 1

Steam, braise, or boil your corned beef. It will take 3 hours on the stove or in a 350-degree oven, 5 hours on high in a crockpot, or 1 hour on high in an Instant Pot. Let the corned beef rest for 30 minutes.

Step 2

Dice the potatoes into ¼ inch cubes and cook in lightly salted boiling water until tender, about 10 minutes. Drain well.

Step 3

Preheat a cast iron skillet over medium high heat. Add butter and potatoes.

Step 4

Chop corned beef into ¼ inch cubes and add to skillet. Stir to combine with potatoes.

Step 5

Add vinegar and spices, and stir well.

Step 6

Reduce heat to medium and let corned beef and potato mix cook for 5 minutes without stirring, so a crust forms.

Step 7

Serve with any style of eggs.
