It is a masterclass in zero-waste Mediterranean cooking, offering a translucent, candy-like crunch that is as beautiful to look at as it is delicious to eat.

🥗 Ingredients

The Fruit Base

  • 1 kg Watermelon Rind (peeled of green skin and red flesh, cut into 1-inch cubes or decorative shapes)
  • 2 tablespoons Pickling Lime (Calcium Hydroxide) or Baking Soda (used to ensure the rind stays crisp)
  • 2 liters Water (for the soaking bath)

The Syrup

  • 1 kg Granulated Sugar (standard white sugar works best for clarity)
  • 3 cups Water (filtered)
  • 2 tablespoons Honey (Greek thyme honey adds a lovely depth)
  • 3 tablespoons Lemon Juice (freshly squeezed)

Aromatics

  • 3-4 leaves Rose Geranium Leaves (Arbaroriza) (fresh; provides the authentic Greek aroma)
  • 1 whole Vanilla Bean (split lengthwise)
  • 1 piece Cinnamon Stick (optional)
  • 1/2 cup Blanched Almonds (whole, toasted for a traditional crunch)

👨‍🍳 Instructions

  1. 1

    Prepare the watermelon rind by slicing off the tough green outer skin with a vegetable peeler and removing all traces of red flesh. Cut the white/pale green rind into 1-inch squares or use a crinkle cutter for a traditional look.

  2. 2

    Dissolve the pickling lime or baking soda in 2 liters of water. Submerge the rind pieces in this solution and let them soak for at least 4 hours (ideally overnight). This step is crucial for achieving the signature 'snap' of a spoon sweet.

  3. 3

    After soaking, rinse the rind pieces thoroughly under cold running water at least 5-6 times to ensure all traces of the lime/soda are removed.

  4. 4

    Place the rind in a large pot of fresh water and bring to a boil. Blanch for 5 minutes, then drain. Repeat this blanching process one more time with fresh water until the rind is slightly translucent but still firm.

  5. 5

    In a heavy-bottomed preserving pot, combine the 1kg of sugar with 3 cups of water. Bring to a boil over medium-high heat, stirring until the sugar is completely dissolved.

  6. 6

    Add the blanched watermelon rind to the syrup. Bring to a simmer and cook for 15 minutes. Remove from heat, cover with a clean cloth, and let it sit for 12 hours (or overnight). This allows the rind to absorb the syrup without collapsing.

  7. 7

    The next day, add the honey, vanilla bean, and cinnamon stick to the pot. Bring back to a boil.

  8. 8

    Simmer the mixture over medium heat for about 35-45 minutes. You are looking for the 'setting point' where the syrup is thick enough to coat a spoon and the rind is completely clear and jewel-like.

  9. 9

    Five minutes before finishing, add the rose geranium leaves, blanched almonds, and the fresh lemon juice. The lemon juice prevents the sugar from crystallizing.

  10. 10

    Perform the 'cold plate test': drop a bit of syrup onto a chilled saucer. If it holds its shape and doesn't run, the sweet is ready.

  11. 11

    Remove the rose geranium leaves and cinnamon stick. Carefully ladle the hot preserves into sterilized glass jars, ensuring the rind pieces are fully submerged in syrup.

  12. 12

    Seal the jars tightly and turn them upside down for 10 minutes to create a vacuum seal, then let them cool completely at room temperature.

💡 Chef's Tips

Use a thick-walled watermelon for the best results, as the rind is meatier. If you cannot find rose geranium, substitute with a teaspoon of rose water added at the very end. Ensure all red flesh is removed; any remaining fruit will become mushy and spoil the texture. Do not rush the soaking process; the lime/soda bath is what creates the unique candied crunch. Store unopened jars in a cool, dark place for up to a year; refrigerate after opening.

🍽️ Serving Suggestions

Serve a single spoonful in a small crystal dish alongside a glass of ice-cold water. Layer over thick, strained Greek yogurt for a sophisticated breakfast or light dessert. Use as a topping for vanilla bean panna cotta or cheesecake. Pair with a strong Greek coffee or a glass of chilled Mastika liqueur. Top a scoop of salty feta cheese for a bold sweet-and-savory appetizer.
