I've tweaked dozens of potato skin recipes, and I believe I've finally perfected this one.

Russet potatoes provide the high starch and low moisture content required for structural integrity. Starch molecules gelatinize during the initial 400 degrees Fahrenheit bake. Lower starch varieties will collapse instead of holding their shape under toppings. Select tubers that feel heavy and feature unblemished skins.
Butter applied to the exterior conducts heat efficiently while the potato bakes. Olive oil is brushed on later because its smoke point handles the subsequent 450 degrees Fahrenheit crisping stage better than butter alone. Leaving an eighth to a quarter inch of flesh determines how rigid the final shell becomes.
Dairy proteins in cheddar and jack undergo the Maillard reaction under the broiler, creating savory compounds. Fat from the cheese and bacon melts into the warm starch matrix. Sour cream introduces lactic acid, which cuts through the heavy lipids of the melted cheese and crisp pork fat.
