Peel potatoes. Cut in half lengthwise; then crosswise into thick chunks. You don't want small pieces because they will cook into a watery mush.
Add the salt. Then add enough water to nearly cover the potatoes.
Cover and cook on high about 4 hours or until potatoes are easily pierced with a fork.
Drain the potatoes well. Keep them in the slow cooker for the remainder of the prep.
Mash the potatoes using an electric hand mixer or with a traditional potato masher.
Add the cheese and mix well with the hand mixer or potato masher. Since the potatoes are hot, most of the cheese will melt. YUM!
Add the sour cream and the paprika. Start out with the smaller amount of the smoked paprika, then taste. Correct seasonings and add-ins to taste. If the potatoes are too thick for your personal preference, thin them with a small amount of warmed milk.
The potatoes can be kept warm in the slow cooker with the slow cooker on low until ready to serve.
