Culinary Notes
The Dryness Danger: Because the meat inside the fat cap is extremely lean, pork loin is unforgiving. If you cook it past 63°C (145°F), the muscle fibres contract and squeeze out all moisture, leaving you with "sawdust" meat. Modern safety standards mean you do not need to cook pork until it is grey; a slight blush of pink in the centre is safe and juicy.
The "Schabowy" Cut: To make the classic Polish Kotlet Schabowy or Austrian Schnitzel, you slice the loin across the grain into discs. However, the meat is dense. You must pound it with a mallet. This breaks the tough muscle fibres, allowing it to cook instantly and tenderising it so it melts in the mouth.
The Fat Cap: When roasting whole, score the fat cap (cut a diamond pattern). This renders the fat, allowing it to drip down and baste the lean meat as it cooks. Never remove the fat before roasting, or the meat will dry out.
Brining: Because it lacks internal marbling, soaking the loin in a saltwater brine (water + salt + sugar + herbs) for 6–12 hours before roasting acts as an insurance policy, forcing water into the cells so it stays moist even if slightly overcooked.
