Slicing raw potatoes directly over a seasoned bowl of heavy cream prevents rapid enzymatic browning while simultaneously coating every individual starch molecule with fat. Russet potatoes, prized for their high starch content, release enough amylose during the nearly two-hour bake to naturally bind the paper-thin layers into a cohesive block without requiring added flour or gelatin. Trimming the raw tubers into uniform rectangles before slicing eliminates rounded edges, ensuring that every resulting portion maintains identical dimensions for even pan-searing later. Maintaining a steady oven temperature of 350 degrees Fahrenheit allows the dairy solids to reduce gently without scorching the parchment lining. Pressing the baked loaf under weighted cans compresses the tender layers into a dense, solid brick as it chills for at least six hours. This extended refrigeration period is non-negotiable; attempting to slice warm potatoes will cause the compressed architecture to disintegrate entirely. When portioning the chilled block into twelve equal pieces, use a sharp, thin-bladed knife wiped clean between cuts to preserve the clean geometric edges. Frying the portions in hot canola oil with crushed garlic cloves and fresh thyme sprigs infuses the fat with aromatics while rendering the exterior aggressively crisp. Basting the bubbling oil directly over the surfaces accelerates the browning reaction across the entire face of each piece. Fresh chives provide a sharp, clean onion bite that cuts cleanly through the rich dairy fats lingering on the palate.
