Study Notes

Doneness

  • Definition of doneness varies depending on cooking method: dry heat or moist heat
  • In dry heat, meat is considered "done" when proteins have coagulated to the proper degree, as indicated by internal temperature
  • In moist heat, meat is considered "done" when connective tissues have broken down sufficiently for the flesh to be edible

Dry-Heat Cooking

  • Intended to achieve necessary degree of doneness while keeping natural softness and juiciness intact
  • Degree of doneness is determined by protein coagulation and internal temperature

Degree of Doneness

  • Red meat (beef, lamb, and mutton) changes color from red to pink to grey or grey-brown as it cooks
  • Rare: browned exterior with a thin layer of cooked meat; red inside
  • Medium: thicker grey layer; pink inside
  • Well: grey throughout
  • White meat (pork) changes color from pink or grey-pink to white or off-white
  • Optimal range of doneness for pork: 71°C to 77°C

Testing Doneness

  • Determining doneness is a crucial component of meat preparation
  • Traditional way to determine doneness is to pierce the meat with a meat fork
  • Meat is done when the fork prongs easily slip in and out

Moist-Heat Cooking

  • Meat is cooked well done and beyond well done
  • Tenderness, not temperature, indicates doneness
  • Low temperatures, no higher than simmering, are required to prevent protein toughening
  • Simmering normally requires an oven temperature of 250°F to 300°F (120°C to 150°C)

Juiciness

  • Three major elements influence juiciness: internal fat, gelatine, and protein coagulation
  • Internal fat makes meat taste juicier
  • Gelatine, derived from connective tissue, aids in binding water molecules and retaining them in the meat
  • Protein coagulation breaks down and loses water as it cooks, leading to moisture loss

Touch

  • Rare: feels soft and squishy, yields to pressure
  • Medium: feels relatively hard and durable, springs back quickly
  • Well done: has a strong feel, does not yield under pressure

Time-Weight Ratio

  • Many charts show roasting times per kilo of meat, but these are only estimates
  • Cooking time is determined by many factors other than weight and oven temperature, including meat temperature, fat cover, bones, oven size, and cut shape
  • Roasting time charts may not be accurate, and experience and judgment are required
