1 tablespoon butter plus 1 tablespoon olive oil (enough to prevent sticking)
2 cups cooked corned beef, finely chopped
3 cups potatoes cubed into about 1/2 inch pieces.
1/2 onion minced
1 clove minced garlic
1 green onion diced
1 poached egg for each serving.
Dollup of vinegar in poaching water
First, get a large skillet and throw in the potatoes and fill with water until the potatoes are just covered. Put on the stove on high heat. Just when the potatoes come to a boil immediately take them off and drain. Turn the heat down to medium high. Add the olive oil and butter and when melted, throw in the potatoes again and give the pan a shake to keep them from sticking a coat them with the oil/butter. Blanching the potatoes like this will ensure that they get cooked through while allowing the outside to get nice and crispy. If you don't do this you will have a nice crispy outside and an uncooked middle. Now leave them alone for a few minutes (4 or 5) until you get a good brown on one side then turn them over. After a couple minutes turn again.
When they start to brown and look close to done, take one out and check it for doneness, it should be cooked through. Turn down the heat to medium, throw in the minced onion and garlic, and mix it up. Cook until the onion is translucent and just started to brown up, then add the corned beef and give it another stir. While that's going start on your poached eggs.
I have a shallow sauce pan I like to poach in but any sauce pan will do. Fill the pan with water and add a dollup of vinegar to help keep the eggs from separating. Let the water come to a boil then turn down until it's just below a boil. You don't want alot of water action, it will break up the egg. I break the eggs into little pyrex bowls before poaching. This allows you to make sure no shells get in, and allows you to gently add the egg by slowly immersing the bowl and letting it slide into the water. I only do two eggs at a time to keep the water from cooling too much and being able to have more control.
Plate your hash and add a poached egg to the mound. Sprinkle with a little bit of the green onion for garnish. If you want you can heat a small bowl of ketchup and serve on the side.
