Sponge (Sea Foam) Toffee
Prep time: 
Cook time: 
Total time: 
Yield: 1 9x9-inch square pan of candy
  • ½ teaspoon gelatin powder
  • 1 teaspoon water
  • 1 ½ cups granulated sugar
  • ½ cup honey (or corn syrup or ¼ cup corn syrup plus ¼ cup honey))
  • ½ cup water
  • 1 tablespoon baking soda (sifted)
  1. Line a 9x9-inch pan with parchment paper, allowing it to extend over the edges.
  2. In a small bowl, sprinkle gelatin over 1 teaspoon water and allow to bloom for 5 minutes.
  3. In a medium pot with high sides, combine sugar, honey (or corn syrup or mix of both) and ½ cup water. Heat and stir over medium heat until sugar dissolves and mixture comes to a boil. Wash down any sugar crystals from the sides with a wet pastry brush. Clip on candy thermometer and heat to 300° F. This should take about 7 to 10 minutes.
  4. Remove from the pot from the heat and let sit for two minutes, bubbling should subside (temperature needs to fall to around 275° F). At this point, microwave the gelatin for 30 seconds to melt. Add gelatin and whisk it in. Be careful, the sugar syrup will bubble up!
  5. Return sugar syrup to the heat and bring temperature back up to 280° F (the temperature will have fallen upon addition of the gelatin). Sprinkle baking soda over syrup and whisk vigorously for 30 seconds. The sugar will rise up to the top of the pot, bubbling like crazy. Again, be careful!!
  6. Quickly pour the bubbling mixture into prepared pan. Do not spread the mixture, just let it settle into the pan. Allow to cool completely (about 2 hours or overnight) before removing from the pan.
  7. Either break into odd pieces or cut into squares (this is a messy process!). To cut into squares - using a serrated knife, score the candy at 1-inch intervals. Snap the candy apart at the score lines.
  8. Dip sponge candies in tempered chocolate, tap off excess. Chill in the fridge to set the chocolate shell. Enjoy!
- Any leftovers will keep for a week if you store the candy between layers of parchment in a sealed container in the refrigerator.
