Boil the sugar to the hard-ball. Remove it from the fire; add the essence of peppermint and stir it just enough to mix in the flavoring and cloud the sugar. Drop it into starch molds or upon an oiled slab, letting four drops of the candy fall in exactly the same spot; it will then spread round and even.
These drops should be translucent or a little white. Unless care is used the candy will grain before the drops are molded; therefore it is better to pour it from the spout of the pan than to dip it out with a spoon.
