Meanwhile, bring 1/2 cup remaining sugar and water to boil in saucepan on medium-high heat, stirring until sugar is dissolved; cook, without stirring, 10 to 12 min. or until golden brown. Remove from heat. Stir in seeds with wooden spoon; cook and stir 4 to 5 min. or until seeds are toasted and evenly coated with sugar syrup. (Note: Sugar will turn dry and grainy before melting completely. Just keep stirring.) Pour carefully onto parchment-covered baking sheet; cool completely.
