Essentially, for the sweet potato recipe, you have two options. Steaming (you don't even need a steamer, just use a large saucepot with a steamer basket over the top) and boiling.
I still find that the boiled option is easier and essentially is my go-to preferred method. Cook the potatoes in a large pot with salted water and some black pepper. Boil until potatoes are fork-tender. About 10-15 minutes. You can either cook whole potatoes or slice them into cubes to reduce cooking time.
Drain well until all the water is removed and evaporated. Return the potatoes to the pot or a large bowl.Add butter to the pot, and whip the potatoes with a hand mixer, whip with a blender (more smooth consistency) over medium speed or use a hand masher for more rustic consistency).
I like to roughly mash the potatoes with a potato masher, then add milk and whip with an electric hand mixer until creamy.
In batches, add warm milk and potatoes constantly whipping the potatoes until all combined and creamy. Season the potatoes with salt, pepper and 1 teaspoon brown sugar.
Meanwhile, cook the bacon in a pan with 1 teaspoon of brown sugar until crumbly. Set aside on paper towels to remove the extra fat. Taste the potatoes for seasoning again and adjust if needed. Serve this classic side dish hot with bacon crumbles and fresh parsley, fresh thyme or rosemary sprigs, and plenty of butter.
