40 seconds for cooked mixtures, as croquettes, codfish balls, etc.
20 seconds for French fried potatoes.
Seconds may be counted thus: one hundred and one, one hundred and two, etc.
The fat may be tested also by dropping into it a little piece of the article to be cooked. When it rises to the top, bubbles vigorously and browns quickly, the fat is hot enough.
When prepared, the foods must be placed in the basket, not too many at a time or too close together, and then lowered gently into the fat. They generally will sink to the bottom for a minute or two, and only float when they have begun to brown. When a bright golden brown, take up the basket and let the fried things drain in it, over the hot fat, for a few seconds. Then take them out gently one by one, and lay them on a sheet of brown or kitchen paper.
The draining over the pan is one of the principal things to attend to; if this be neglected, the fat will cling about the fried things, making them both look and taste greasy, whereas if properly drained in the basket to begin with, they will afterwards scarcely mark the paper. When, as is sometimes the case, no frying basket is used, each thing fried should be drained between a spoon and the edge of the pan.
To Clarify
It is economy to use three pounds in the kettle, clarifying the fat when it is put away. To clarify Crisco, take that which has been used for deep frying and when it has cooled, but not solidified, strain through a double thickness of cheese cloth, replace kettle on stove, drop several slices of potato into the Crisco and reheat.
When the potatoes are golden brown, take out and pour the Crisco back into the tin. With this little care, fish, oysters, onions, chops, fritters, doughnuts, etc., may be fried over and over again in the same Crisco.
