• 2 cups granulated sugar
  • 2 tbsp cornstarch
  • 1 tsp salt
  • 2/3 cup water
  • 9 oz light corn syrup
  • 1 tsp vanilla extract
  • Green gel food coloring
  • Red gel food coloring
  • 2 tbsp butter, plus more for buttering hands and paper
  • 1 tbsp black sesame seeds


  1. Put the sugar, cornstarch, salt, water and corn syrup into a large saucepan. Heat over a low heat and stir until the sugar granules have dissolved. Turn up heat to medium, and leave it to come to a boil and heat up until it reaches 255 degrees. Let it stand for 5 minutes, then stir through the vanilla extract.
  2. Pour half of the mixture into another saucepan. Add a few drops of green food coloring to one, and a few red to another. Stir well. (The color fades when you stretch it so aim for a bit more vibrant than your intended end result.)
  3. Generously butter each small oven dish, then mix the sesame seeds through the red mixture and pour that into one dish. Pour the green mixture into the other.
  4. While the taffy is cooling, lay out a large piece of baking parchment and rub butter all over it. Have a pot of butter ready to keep buttering your hands while you stretch the taffy. After 15 to 20 minutes, the taffy mixtures will be cool enough to handle, and solid enough to hold their shape.
  5. Keep your hands well buttered at all times or the candy will stick to your fingers.
  6. Working with the red taffy first, pick it up and stretch it, then fold it back on itself. Keep doing so for around 5 minutes, until it is lighter in color and firm enough to hold its shape.
  7. Spilt this red mixture in two, and shape each into a sausage around 16 inches long. Lay them onto the buttered parchment, then press each down at the sides to create a semi-circle shape.
  8. Now repeat the stretching process with the green taffy, then lay it between two sheets of buttered parchment and roll it out into a rectangle 16 inches long and around 6 inches across.
  9. Use a buttered pizza cutter to cut this piece into two even strips, then lay each over a the pink strips and flatten them down with your fingers. Trim any excess green bits with the pizza roller again.
  10. Use a small serrated knife to cut the taffy into little watermelon slices.
  11. Wrap each in a square of parchment and twist the ends. Let the taffy cool completely before eating.
