TO CHOOSE FISH.
Copper Fish or Ham Kettle.
The cook should be well acquainted with the signs of freshness and good condition in fish, as they are most unwholesome articles of food when stale, and many of them are also dangerous eating when they are out of season. The eyes should always be bright, the gills of a fine clear red, the body stiff, the flesh firm, yet elastic to the touch, and the smell not disagreeable.
When all these marks are reversed, and the eyes are sunken, the gills very dark in hue, the fish itself flabby and of offensive odour, it is bad, and should be avoided. The chloride of soda, will, it is true, restore it to a tolerably eatable state,[[42]] if it be not very much over-kept, but it will never resemble in quality and wholesomeness fish which is fresh from the water.
[42]. We have known this applied very successfully to salmon which from some hours’ keeping in sultry weather had acquired a slight degree of taint, of which no trace remained after it was dressed; as a general rule, however, fish which is not wholesomely fresh should be rejected for the table.
Mackerel Kettle.
A good turbot is thick, and full fleshed, and the under side is of a pale cream colour or yellowish white; when this is of a bluish tint, and the fish is thin and soft, it should be rejected. The same observations apply equally to soles.
The best salmon and cod fish are known by a small head, very thick shoulders, and a small tail; the scales of the former should be bright, and its flesh of a fine red colour; to be eaten in perfection it should be dressed as soon as it is caught, before the curd (or white substance which lies between the flakes of flesh) has melted and rendered the fish oily. In that state it is really crimp, but continues so only for a very few hours; and it bears therefore a much higher price in the London market then, than when mellowed by having been kept a day or two.
