The fire that is but just sufficient to receive the noble sirloin ([No. 19]), will parch up a lighter joint.
From half an hour to an hour before you begin to roast, prepare the fire by putting a few coals on, which will be sufficiently lighted by the time you wish to make use of your fire; between the bars, and on the top, put small or large coals, according to the bulk of the joint, and the time the fire is required to be strong; after which, throw the cinders (wetted) at the back.
Never put meat down to a burned-up fire, if you can possibly avoid it; but should the fire become fierce, place the spit at a considerable distance, and allow a little more time.
Preserve the fat,[75-*] by covering it with paper, for this purpose called “kitchen-paper,” and tie it on with fine twine; pins and skewers can by no means be allowed; they are so many taps to let out the gravy: besides, the paper often starts from them and catches fire, to the great injury of the meat.
If the thing to be roasted be thin and tender, the fire should be little and brisk: when you have a large joint to roast, make up a sound, strong fire, equally good in every part of the grate, or your meat cannot be equally roasted, nor have that uniform colour which constitutes the beauty of good roasting.
Give the fire a good stirring before you lay the joint down; examine it from time to time while the spit is going round; keep it clear at the bottom, and take care there are no smoky coals in the front, which will spoil the look and taste of the meat, and hinder it from roasting evenly.
When the joint to be roasted is thicker at one end than the other, place the spit slanting, with the thickest part nearest the fire.
Do not put meat too near the fire at first; the larger the joint, the farther it must be kept from the fire: if once it gets scorched, the outside will become hard, and acquire a disagreeable, empyreumatic taste; and the fire being prevented from penetrating into it, the meat will appear done before it is little more than half-done, besides losing the pale brown colour, which it is the beauty of roasted meat to have.
From 14 to 10 inches is the usual distance at which meat is put from the grate, when first put down. It is extremely difficult to offer any thing like an accurate general rule for this, it depends so much upon the size of the fire, and of that of the thing to be roasted.
Till some culinary philosopher shall invent a thermometer to ascertain the heat of the fire, and a graduated spit-rack to regulate the distance from it, the process of roasting is attended by so many ever-varying circumstances, that it must remain among those which can only be performed well, by frequent practice and attentive observation.
