Mix the first five ingredients well, boil until brittle when tested in cold water (about 20 minutes).
Using a candy thermometer, this would be about 300 to 310F degrees.
Be careful! This burns easily.
Beat 2 egg whites until stiff.
Pour the boiling syrup over the stiff egg whites, beating fast.
Continue beating until candy starts to set (must be pretty stiff).
Add vanilla or flavoring and coloring and beat until thoroughly mixed.
Drop by spoonfuls onto oiled pan.
The candy should be soft and chewy but hold its shape like a Hershey's Kiss.
Notes
Note 1: I have found two "Old Fashioned Sea Foam" recipes that say to add vinegar. One says 2 teaspoons and the other says 1 tablespoon. I have not tried it.Note 2: Mom may also have added the vanilla at the end while whipping the candy. Some recipes say to do it this way.Note 3:I'm pretty sure the weather must be cold and dry for this candy to turn out.
