How to Make Watermelon Simple Syrup

There are two methods for making watermelon simple syrup: the cold process and the hot process. Both techniques produce delicious results, but they offer slightly different flavor profiles. Here’s how to make watermelon simple syrup using each method:

Cold Process Method

– 1 lb fresh watermelon, rind and seeds removed
– 8 oz granulated sugar

  1. Cut the fresh watermelon into ½ inch cubes.
  2. Place watermelon cubes in a bowl or airtight container.
  3. Add the granulated sugar to the bowl and stir gently to coat the watermelon evenly.
  4. Close the container and refrigerate overnight or up to 24 hours. During this time, the sugar will draw the liquid out of the watermelon.
  5. After the resting period, strain the liquid into a separate bowl, leaving the watermelon pieces behind.
  6. Dissolve any remaining sugar by gently stirring the liquid.
  7. Pour the watermelon simple syrup into a bottle or pitcher.
  8. Store in the refrigerator for up to 10 days.

Hot Process Method

– 1 large or 2 small watermelons
– 14 oz granulated sugar
– 1 cup water

  1. Remove the rind and seeds from the watermelon and cut the flesh into ½-inch cubes.
  2. In a medium saucepan, combine watermelon cubes, granulated sugar and water.
  3. Bring to a boil, stirring constantly to dissolve the sugar.
  4. Reduce the heat and simmer for about 30 minutes or until the watermelon loses its color.
  5. Strain the liquid into a second saucepan, discarding the watermelon pieces.
  6. Cook the liquid for about 15 minutes, or until reduced by about half.
  7. Allow the syrup to cool completely before transferring it to a bottle.
  8. Watermelon Simple Syrup will keep in the refrigerator for 1-2 weeks.

Storing Watermelon Simple Syrup

Store-bought watermelon syrup usually contains preservatives and can be stored at room temperature even after opening. However, homemade watermelon syrup does not contain preservatives and has a shorter shelf life. Here’s how to store your homemade watermelon syrup:

  1. Refrigeration: Homemade watermelon simple syrup will keep in the refrigerator for about a week. After this time, it is advisable to discard any remaining syrup to prevent mold growth.
  2. Freezing: If you have a large batch of watermelon syrup or want to extend its shelf life, you can freeze it. Transfer the syrup to an airtight container or ice cube tray and place in the freezer. When ready to use, thaw the syrup overnight in the refrigerator or gently heat on the stovetop.


Making your own watermelon simple syrup is a delightful way to capture the essence of summer in a concentrated and versatile form. Whether you use it to enhance your favorite cocktails, add a fruity twist to desserts, or elevate your baking, watermelon simple syrup offers endless possibilities for creative culinary exploration. With cold and hot process methods at your disposal, you can choose the flavor profile that suits your preferences. So why not indulge in the vibrant and refreshing flavor of watermelon by creating your own homemade watermelon simple syrup? It’s the perfect way to elevate your culinary creations and enjoy the flavors of summer all year long.
