Swapping red potatoes for russets fundamentally alters the final dish. Waxy red cultivars hold their shape under pressure because they contain less starch than mealy baking potatoes. They absorb dressings evenly without crumbling into mush. Cooled starches retrograde during refrigeration, which firms the cellular walls of the potato. This chemical shift makes day-old batches structurally superior to freshly tossed ones.
Boil the diced tubers in salted water until a paring knife slides into the center with zero resistance. Drain them thoroughly in a colander to prevent excess moisture from diluting the dressing. Render the bacon over medium-low heat to extract maximum fat without scorching the protein solids. Whisking mayonnaise directly into warm bacon drippings emulsifies the fats instantly. Pour this warm mixture over the vegetables while the potatoes are still receptive to absorption. Chill the bowl for at least two hours before serving to let the flavors coalesce.
