Roast suckling pig (cochon de lait) is the grand centrepiece of French celebratory tables — a whole milk-fed piglet (4-6kg, under 6 weeks old), spit-roasted or oven-roasted until the skin achieves a glass-like, shatteringly crisp crackling over meat so tender it falls from the bone. The piglet's youth is key: fed exclusively on mother's milk, its flesh is pale, sweet, extraordinarily tender (the collagen has not yet toughened), and almost entirely free of the porky flavour of mature pigs. Preparation: scald the piglet in 70°C water for 30 seconds and scrape all remaining hair with a blunt knife. Score the skin in a fine crosshatch (1cm intervals, 3mm deep). Dry the skin thoroughly — moisture is the enemy of crackling. Rub the exterior with oil and coarse salt; stuff the cavity with sage, garlic, onion, and bread soaked in milk (the traditional farce). For spit-roasting: truss securely, spit through from mouth to tail, and roast before a moderate fire (200°C equivalent) for 2-2.5 hours, basting constantly with the drippings. For oven-roasting: place on a rack in a large roasting pan at 220°C for 30 minutes (to begin crackling), then reduce to 170°C for 2-2.5 hours (25-30 minutes per kg). Baste every 15 minutes. The skin must reach 180°C+ for the Maillard and glass-transition reactions that produce true crackling — below this, it remains leathery. Internal thigh temperature: 75°C (piglet must be cooked through). Rest 20 minutes. Present whole at the table, with an apple in the mouth (tradition), and carve tableside.
Milk-fed piglet under 6 weeks — the diet determines the delicate flavour and pale flesh Dry skin is essential for crackling — scald, scrape, pat dry, and air-dry in refrigerator if possible Score the skin finely — this allows fat to render and the skin to blister evenly Constant basting maintains moisture in the lean meat Cook to 75°C internal — young pork must be cooked through but remains tender due to its youth
Brush the scored skin with rice vinegar or lemon juice before salting — the acid tightens the collagen in the skin, promoting blistering and crackling For absolute crackling perfection, pour boiling water over the skin before drying — the thermal shock causes the surface to contract and then re-relax, creating the micro-texture that blisters during roasting A final 5-minute blast under the grill at 250°C after the roast is rested produces any remaining soft patches into crackling
Using a piglet that is too large (over 6kg) — it is no longer a suckling pig and the meat loses its delicacy Wet skin that steams instead of crisping — the crackling will be soft and chewy Insufficient scoring — unscored skin bubbles unevenly and remains tough in patches Not basting — the lean, young meat dries out rapidly without regular fat application Carving in the kitchen — the whole presentation at the table is the theatrical point of the dish
