One of the Greatest Potato Dishes Ever

Lamination and Compression\n\nThe foundation of this dish relies on starch control and precise lamination. Rather than standard roasting or frying, potatoes are finely sliced on a mandoline and layered meticulously with rendered fat—such as beef fat or duck fat—and seasoning. This builds a multi-layered structure reminiscent of a classic pavé. The layered potato block is then baked until tender, allowing the natural starches to bond the layers together. Crucially, the potatoes must be pressed under heavy weights while cooling. This compression step is non-negotiable; it forces out excess moisture and packs the layers into a dense, cohesive block that can be cleanly portioned without splintering during service.\n\n## Precision Portioning and Deep Frying\n\nOnce fully chilled and set, the compressed potato block is portioned into uniform rectangles or batons. Clean, sharp cuts are essential here to expose the laminations, which open up like pages of a book when fried. The portioned potatoes are deep-fried in hot oil. The moisture between the micro-layers rapidly turns to steam, puffing the layers apart and creating an incredibly crispy exterior while keeping the center rich and creamy. Managing the frying temperature is key: too hot and the exterior burns before the cold core warms through; too cool and the potato absorbs excess oil, losing its structural integrity.\n\n## Starch and Fat Selection\n\nFor this technique, choosing the right potato variety is paramount. A high-starch, floury potato is essential to provide the necessary binding power. Waxy potatoes will not release enough starch to fuse the layers, causing the block to fall apart when sliced or fried. The fat used for lamination not only adds flavor but also lubricates the layers, ensuring they separate slightly during the fry stage. Rendered beef fat or clarified butter works best, offering a high smoke point and deep, savory notes that complement the natural potato sugars. Season immediately out of the fryer with an acidic, umami-rich powder to cut through the richness of the fat.
