Enquire within upon everything by Robert Kemp Philp

The meat should be firm and close in grain, and red in colour, the fat white and firm. Mutton is in its prime when the sheep is about five years old, though it is often killed much younger. If too young, the flesh feels tender when pinched; if too old, on being pinched it wrinkles up, and so remains. In young mutton, the fat readily separates; in old, it is held together by strings of skin. In sheep diseased of the rot, the flesh is very pale-coloured, the fat inclining to yellow; the meat appears loose from the bone, and, if squeezed, drops of water ooze out from the grains; after cooking, the meat drops clean away from the bones. Wether mutton is preferred to that of the ewe; it may be known by the lump of fat on the inside of the thigh.
