Homemade Watermelon Ice Cream

My youngest son is always bringing me fun ideas he finds on tik-tok. He always wants to try them out, and sometimes we do it just for fun. This time, however, I thought the idea would be a great one to share with you all – that is if the recipe was any good. Sometimes, what looks good behind the camera is not always the tried and true version.

With that said, I did have to make a couple of modifications to the fun idea. I tweaked the recipe, a little bit and ditched serving it by slicing a frozen rind into watermelon pieces. Let me tell you, that was nearly impossible and frustrating – to say the least. No worries, it’s just as much fun to scoop watermelon-flavored ice cream out of a rind.

Things I love about this Recipe:

• It’s simple to make
• there are only three ingredients that are really easy to find
• it’s a no-churn recipe that is done quickly
• the kids can help make this yummy recipe

FAQs

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

How do I find a Sweet Watermelon?

• 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
• find a watermelon dull in color and shine – The more shine means it’s still too young

Tips and Tricks:

• make sure you strain the watermelon after blending it. This will get rid of pulp and most of the seeds
• you can make this recipe in any order that you want – just make sure the heavy cream is at a soft peak before adding in the other ingredients
• make this the day before your party, or better yet – two days
• if you make this watermelon overnight, the next morning you can expect the top half to be firm, but it may be slushy in the middle and even have juice standing in the bottom. This is fine for a fun treat, but if you are serving at a party you might want to let it freeze for at least 1 day in advance to ensure it is frozen through
• you can try to cut the rind and make watermelon slices, but I don’t recommend it. The frozen rind is as hard as a rock. You’ll have to work very hard to achieve this and to me, it’s not worth it. Just scoop the ice cream and enjoy
• trying to find a sweet ripe seedless watermelon. The more flavor the watermelon has, the more flavor your ice cream will have
• leaving some flesh on the rind. It will help flavor the ice cream as it freezes

• 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
