Starchy russet potatoes drive the texture of this thick soup, releasing cellular components as they break down into the dairy base. Selecting high-starch baking tubers ensures that the interior yields a fluffy, absorbent pulp capable of soaking up butter, cream, and milk without turning gluey. When incorporating the flour and butter roux, cook the mixture for exactly one minute over medium heat to eliminate the raw cereal taste while maintaining maximum thickening power. Whisking cold milk gradually into the hot fat prevents lumps from forming, establishing a smooth foundation before any solid ingredients enter the pot. Utilizing a hand-held potato masher directly in the dairy mixture allows precise control over particle size, leaving enough small chunks for rustic mouthfeel while releasing sufficient starch to naturally body the liquid. If the finished consistency feels too dense after incorporating the cheddar and sour cream, thin the batch incrementally with extra milk heated to a simmer rather than cold dairy, which can break the emulsion. When pairing side dishes with such a rich, high-fat profile, crisp salads dressed in sharp vinaigrettes containing lemon juice or apple cider vinegar cut through the heaviness and cleanse the palate between rich bites. Thinly sliced radishes or lightly pickled red onions also provide the necessary acidic contrast to balance the dairy-heavy foundation. Originally rooted in American comfort food traditions that repurpose leftover jacket potatoes into hearty cold-weather meals, this preparation rewards careful temperature management. Leftovers keep safely in an airtight container in the refrigerator for up to three days, though the starches will continue to absorb liquid, requiring a splash of milk during reheating.
