This is the most difficult part in the science of cooking. To season is not difficult, but to season properly is quite another thing.
It is not only necessary to know well how to stew or roast a peace of meat or any thing else, but to know how to season it, to be able to judge what quantity and what kind of spices can be used to season such or such a dish, to what extent all the spices used agree together, and what taste and flavor they will give to the object with which they are cooked; for, if not properly used, they may just as likely destroy the taste and flavor of the object as improve it.
Some dishes require high and much seasoning, others just the contrary. With a good fire and a good spit, it is not necessary to be a thorough cook to roast a piece well, but the cook is indispensable to mix the gravy or sauce with the proper seasonings.
