My hubby is a Grapefruit fan and requested this version of syrup to replicate one of his favorite name brand sodas. This is a non-diet version, but still not overly sweet.


  1. Slice Grapefruit into 1/4 inch rounds. (Discard ends and any slices that have too much pith.).
  2. Place all ingredients in a saute pan and bring to a boil.
  3. Boil gently for 5 minutes, stirring intermittently. (I used a fork to make sure the fruit slices were stirred around evenly and changed them up from top to bottom a bit to ensure all were cooked into the mix thoroughly.).
  4. Remove from heat and remove grapefruit slices, squeezing gently to get out most of the juice.
  5. Mix 1/2 Cup of the syrup with 1 Liter of carbonated water.
  6. Store remaining syrup in bottle or airtight container.
