1poundpeeled and thinly sliced Yukon gold potatoes
salt and pepper to taste
Instructions
Add the whole milk and 1 stick of butter to a small size pot over very low heat to keep warm. You basically want to warm the milk and melt the butter.
Add 2 tablespoons of the butter to a large frying pan or rondeau over medium heat and sear the sausage for 2-3 minutes per side to get a good brown sear on them. Do not worry about cooking completely through at this stage.
Remove the sausage, add in the remaining 2 tablespoons of butter to the pan, and then cook the onions over medium heat until they are lightly browned and translucent, which takes about 10 minutes.
Stir in the garlic and cook for 1 minute and then deglaze with red wine and cook until it is almost gone.
Stir in flour to make a roux and then pour in the beef stock and cook over high heat to a boil to activate the roux to thicken up the gravy.
Turn the heat down to low and finish the gravy with balsamic vinegar, Worcestershire sauce, salt, and pepper, and add the sausage back in and keep warm over low heat.
Next, add the potatoes to a large pot of boiling salted water and cook for 6 to 7 minutes or until tender.
Transfer the potatoes to a food mill and mash.
Finish the potatoes by pouring in the hot milk and melted butter and season with salt and pepper and mix with a spoon or rubber spatula until combined.
Serve the cooked bangers with the mashed potatoes and gravy and garnish with optional chopped fresh parsley.
Notes
Make-Ahead: This recipe is meant to be eaten as soon as it is done cooking. However, you can keep the bangers in the sauce warm as well as the mashed potatoes covered over low heat in their respective pans.How to Store: Keep the bangers and gravy separate from the mashed potatoes and cover and place in the refrigerator for up to 5 days. The sauce and the mashed potatoes will not freeze well.How to Reheat: Place the desired number of mashed potatoes in a small pot with a few tablespoons of whole milk and cook over low heat while occasionally stirring until hot. In a separate pot or pan add the desired number of bangers and sauce and reheat over low heat until hot.In place of a food mill, use a hand masher or electric hand beaters.You can enhance the flavor of the mashed potatoes by substituting the milk for half and half or heavy whipping cream.Cabernet sauvignon, merlot, or cabernet franc work well for the red wine.
