Materials

  • ½ seedless round watermelon Look for a sweet and flavorful melon. Tips are below. Amount: You will ultimately need about 4 cups of strained watermelon liquid from the watermelon
  • 2 cups heavy cream
  • ½ cup sweetened condensed milk

Instructions

  • scoop out the watermelon flesh - leaving about 1/2 inch of flesh on the rind for added flavor
  • place watermelon flesh in the blender and blend until liquified
  • place a strainer over a medium-sized bowl and pour the liquid through the strainer
  • strain as much liquid as you can - you are ultimately trying to get about 4 cups of liquid from the watermelon for this recipe
  • in a stand-up mixing bowl or using an electric mixer and bowl, whip the heavy cream at a fast speed until soft peaks form
  • to the whipped cream, add about 4 cups of juice and the condensed milk
  • mix well
  • pour into the watermelon rind (do not cover) and freeze overnight

Notes

Nutrition facts are only an estimate 

How do I find a Sweet Watermelon?

  • try to find one that is uniform in shape. It can be round or oval, just not irregular
  • look for a super heavy watermelon. This means it has more water content and is probably more sweet
  • find a field spot, which is a round white, brown, or yellow spot on the watermelon is something to look for. Find one that is darker in color - either yellow or brown. That means it has been on the vine longer and is sweeter
  • go for large webbing - a large spider-like web on the watermelon is a sign of it leaking sweetness which is a good sign
  • try to find a watermelon dull in color and shine - The more shine means it's still too young

Watermelon Size:

Tip - Don't worry too much about the size. You'd be surprised at how much liquid you can get out of a small watermelon. Concentrate more on finding a sweet, ripe melon.
  • Round Seedless Watermelons are generally small (around 10-15 lbs.), but their size and proportion can still vary. Personal watermelons are really tiny, and just like the name implies, they are enough to feed yourself. Oblong-seeded watermelons are large (usually about 20-30 lbs.)
  • Round seedless watermelons are not perfectly round, they will still be somewhat oblong
  • You should end up with about 4 cups of strained watermelon liquid, so if you don't have that in your first half, then you might have to scoop out more from the other half to achieve that. On the flip side, if you wind up with too much juice then you might have to use the excess for a drink. 
  • Specific measurements from a watermelon like the one I used in the recipe are about 15 lbs., 16 inches long, and 27 inches in circumference

Make-Ahead and Storage:

Can I make Watermelon Ice Cream ahead of time?

Yes! This ice cream is better if you make it at least twenty-four hours in advance

How long does homemade ice cream last in the freezer?

Homemade ice cream can last up to two weeks in the freezer
Storage: Store homemade ice cream in a sealed container in the freezer

Can I store this watermelon ice cream in the rind?

Yes - for a certain amount of time. After a couple of days, I would transfer the ice cream to an air-tight freezer-proof container for storage in the freezer
