6 British style bangers (or sausages of your choice)
Olive oil (for sautéing)
Instructions
Peel and chop the potatoes into 1-inch cubes and place into a medium-sized pot. Add cold water to cover the potatoes by about 2 inches. Cover with the lid and bring to a boil over high heat. Once the water boils, remove the lid, lower the temperature to medium and continue to boil until the potatoes are fork tender (about 12 minutes).
Drain the potatoes. Add milk, half and half, 2 tablespoons butter, salt and pepper. Mash the potatoes to the desired consistency.
To prepare the gravy—while the potatoes are cooking you can prepare the gravy. In a large deep skillet melt 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons plus 1 teaspoon of flour. Allow the mixture to cook for about 2-3 minutes, whisking constantly.
Slowly add in the ½ cup of Guinness and a ¾ cup of beef stock while continuing to whisk. Add in mustard, Worcestershire sauce, ½ teaspoon salt, ¼ teaspoon garlic powder, and ¼ teaspoon onion powder. Allow the gravy to come to a boil, continuing to whisk constantly. Once the gravy thickens, drop the heat to low, cover and keep warm.
Start to cook the sausages and when the potatoes have about 5 minutes left. Heat a medium skillet over medium heat. Add in 1 tablespoon of olive oil. Heat the oil, then add the sausages. Cook the sausages turning every couple of minutes until browned and fully cooked (the internal temperature has reached 160 degrees F. if using pork).
To assemble—Divide the mashed potatoes into serving bowls. Place a banner on top of potatoes and cover with gravy.
