How to Make It
Combine first 5 ingredients in a large heavy saucepan. Cook over low heat, stirring gently, 10 minutes or until sugar dissolves. Cover and cook over medium heat 2 to 3 minutes to wash down sugar crystals from sides of pan. Uncover and cook, stirring constantly, until a candy thermometer registers 235°F (soft ball stage).
Remove from heat, and stir in baking soda. Beat with a wooden spoon just until mixture begins to thicken. Working rapidly, drop by tablespoonfuls onto parchment paper; let stand 30 minutes or until firm.
