Cucamelon recipes are a treat! Also known as Mexican Sour Gherkins, Mexican Miniature Watermelons, and Watermelon Cucumbers — they’re delicious marinated in Ponzu sauce with a bit of heat. A perfect refreshing, light and flavorful side or snack.
The first time I laid eyes on these Cucamelons, I thought they were teeny-tiny watermelons. It’s no wonder some refer to them as Mexican Miniature Watermelons.
At first glance they’re super cute — and when you take a closer look, maybe even slice one in half, they’re truly exquisite.
What are Cucamelons?
- As I mentioned, they’re also referred to as Mexican Sour Gherkins, Mexican Miniature Watermelons and Watermelon Cucumbers.
- More or less the size of grapes, they’re in season in August and September, and are a considered a delicacy in central America and Mexico, where they are native.
- Even though it sounds like it, these cute fruits are not a hybrid of a watermelon and a cucumber. They are a fruit that grows on a vine called Melothria Scabra, and have been around for centuries.
- A more vibrant green inside than other cucumber varieties, and a wide range of green hues blended into soft stripes on the outside.
- Cucamelon recipes are quite healthy because these babies (pun intended) are packed with vitamins, minerals, antioxidants and fiber. And of course, they are low in calories, too.
What do Cucamelons/Mexican Sour Gherkins taste like?
- Despite the name, they are only a tiny bit sour — subtly lemony.
- They’re also a bit sweet, and have a fantastic crunch.
- More than anything though, they taste like a cucumber.
Where to buy them?
During their season (August and September) your best bet is at your local Farmers Markets, and maybe in the specialty section of the produce department.
You can also order cucamelon seeds from a variety of places including here.
Cucamelon Recipes
These beautiful cuties make for an excellent snack, a superb crunch in a salad, divine pickled in a jar — and perfect marinated in Ponzu!
What is Ponzu sauce?
- Ponzu sauce is a Japanese citrus based sauce or marinade — it’s deliciously sweet, sour, salty, and bitter all at once.
- The ingredients in Ponzu sauce are typically: a citrus called Yuzu, rice wine vinegar, bonito flakes, and seaweed. (I used a few of these and lime juice instead of the Yuzu.)
Tips for Making Ponzu-Marinated Cucamelon Recipe
- You can use the ingredients in my recipe to make the Yuzu sauce, or you can purchase a prepared one.
- If lime isn’t your favorite, you can use lemon instead.
- I like this best after about 30 minutes of marinating time — however, it will still be delicious even the next day.
Enjoy!

Cathy @ She Paused 4 Thought says
I bought some of those at the Santa Monica Farmer’s Market and didn’t know what to do with them, so I just ate them raw on a salad. Next time I see them I will try your recipe. 🙂
valentina says
Hope you enjoy! 🙂
Jennifer says
I’ve never heard of them before. They’re so cute! And I bet, like you said, they’d make exquisite pickles. I want them!
valentina says
If you pickle them, let me know how you like them. Enjoy! 🙂
Irina @ wandercrush says
These are so beautiful! I’ve never even seen such cucumbers before. Ah and I love a good Asian pickle recipe… perhaps my cukes will not be so exotic, but this recipe will definitely be going in my repertoire.
valentina says
Thanks so much, Irina. 🙂
Deb says
We’re still screaming summer sunshine here with lots of fantastic ripe cucumbers that are in need of a refreshing recipe. Thank you for sharing this recipe that is just bursting with bright flavor!

Thank you Deb, for your sunny, bright comments. 🙂
Ash-foodfashionparty says
You have no idea how happy I am to see this on your blog. I love love watermelon cucumbers, this is a completely new recipe to me. We make a dry spicy side out of this vegetable and it is a tedious job to chop em’ up, but I never get tired of chopping my favorite vegetable. Thanks for sharing.
valentina says
Let me know if you post your spicy side of the cucumbers — I bet it’s amazingly delicious! 🙂
Coco in the Kitchen says
Ponzu is great. Pour some on my shoe and I’d eat it!
These are the cutest li’l things!
I’ve gotta get my hands on some, V.
valentina says
Colette – you are too funny. Don’t eat shoes! 😉 I bet your little one would love these.
valentina says
I could just look at them, they’re so adorable. 😉

What a refreshing salad or appetizer this would make! They are cute, but they are also tasty!

Yes, so cute & tasty!

Valentina, these little cucumelons are so cute! They sound amazing and I can’t wait to try them. I’ll have to look for them at the market. Love how you marinated them in ponzu!

Thanks, Kelly! They are indeed cute. 🙂 ~Valentina
Dawn - Girl Heart Food says
I’ve never seen cucamelons around here before, nor have I tried them, but would love to! I do enjoy those little mini gherkins so I bet I’d love this too! Nice touch with the chili flakes – love a little heat 🙂 Have a wonderful week!
valentina says
Thanks, Dawn. Maybe they’ll show up over there one day. Hope you have a wonderful week, too! 🙂 ~Valentina
David @ Spiced says
Well I learned something today! I’ve never heard of cucamelons, but now I really want to try ’em! What a fun flavor combination, and these would be great for a summer party. Love this recipe, my friend!
valentina says
Yes, awesome for a party! Thanks, David. Have a great week. ~Valentina
Marissa says
These are adorable and sound so good! I hope I can find them locally!
valentina says
Me too!! 🙂 Thanks!
Eha says
Well, if so many Americans have never heard of these beauties methinks you’ll believe I have never sighted them Down Under. However having been born in Northern Europe which does not know how to eat without small pickled cucumbers on the table methinks I’ll happily try what Ponzu dressing, which is a firm favourite, will add to the tiny cucumbers I can access here . . . thanks !
valentina says
Thank you, Eha. Tiny cucumbers will be delicious. Yes, these cuties do not show up everywhere. It seems a lot of people grow them in their yards, and I’m hoping to do just that next summer. 🙂 Enjoy.
David Scott Allen says
Even after all the years since you originally posted this, I have still yet to see these in any store in Tucson! I’m so bummed, because these look wonderful!
valentina says
Hmmmmm? I’m going to see if Melissa’s Produces distributes them to any stores out your way. I’ll let you know.
valentina says
Well, unfortunately Melissa’s Produce doesn’t have them this year — they say the best place to look it at the local Farmers Markets. Here’s hoping! And if you’re so inclined . . . . you can get the seeds here. 😀
Missy says
I’m growing cucamelons in my garden for the first time, this year, and this sounds delicious! I’m excited to try this once I’ve got a harvest!
valentina says
Thanks for your note, Missy. I hope you love the recipe! :-)~Valentina
Rebecca says
I’m growing cucamelons in my garden this year and on my second harvest I have enough to fill a pint jar. I did pickle some last week and they were definitely tasty. How long does your recipe keep for?
valentina says
Hi Rebecca, thanks for writing in. 🙂 This will last about 7 to 10 days very well in the refrigerator in a tightly sealed container. So great you’re growing them at home! Enjoy and thanks for checking out my recipes. ~Valentina
