Procure from the butcher's a small piece of rennet, which is the stomach of the calf, taken as soon as it is killed, scoured, and well rubbed with salt, and stretched on sticks to dry. Pour some boiling water on the rennet, and let it remain for 6 hours; then use the liquor to turn the milk. The milk should be warm and fresh from the cow: if allowed to cool, it must be heated till it is of a degree quite equal to new milk; but do not let it be too hot. About a tablespoonful or rather more, would be sufficient to turn the above proportion of milk into curds and whey; and whilst the milk is turning, let it be kept in rather a warm place.
Time: From 2 to 3 hours to turn the milk.
Seasonable at any time.
