Rennet Whey

Warm a pint of milk, but do not let it get too hot, or it will spoil the taste of the whey. Wash the salt from a piece of rennet the size of a dollar, and put it in the milk; when it turns, take out the rennet; wash and put it in a cup of water, and it will do to use again to make whey. If you have rennet in a bottle of wine, two tea-spoonsful of it will make a quart of whey; but if the person has fever, it is best to make it without wine.
