Blackberry Keto Mojito

Skip the Tips and go Straight to the Recipe

I don’t know about where you live, but in Tennessee, it’s hot!

Summer is officially here.

That means yard work, pool parties, and all sorts of outdoor activities that require libation.

When Rebecca and I went Keto, I thought I would have to give up one of my favorite Summer-time adult beverages… the Mojito.

I should have had more faith in the wonderfully creative, evil genius I’m married to!

Rebecca took one of Heaven’s own fruits, combined it with my beloved hot-weather drink, figured how to remove the carbs, and created an elixir fit for a King; or at least, a guy who features himself as the lord of his own domain… or yard. You get the idea.

She made me a freakin’ Blackberry Keto Mojito!!!!

Y’all, the only thing sexier than this drink is the beautifully sweet redhead who made it!

Let me tell you how she did it.

The Ingredients

Fresh Blackberries: Nothing fancy here. Just get some nice, fresh ones at your local grocery. A whole cup of these badass berries only has 6 net carbs; or roughly .3g per blackberry. And we’re not using a whole cup for this recipe.

Powdered Monk Fruit

We use this stuff a lot. It’s a natural, calorie free, carb free sweetener with some great health benefits and none of the side effects of artificial sweeteners or sugar alcohols.

Check out this article to read more about the health benefits of Monk Fruit. 

Monk fruit tastes good without a tinny aftertaste, and it also dissolves well in water which makes it great for this recipe!


If you don’t grow your own (because it’s super easy and you should!) just pick up some whole mint leaves at the grocery. You can typically find them in the cooler section with the other veggies. 2 leaves will add about .2 net carbs to this drink.


This is easy mode. Get a fresh one at the grocery. 1 tablespoon of lime juice has about 1 net carb in it. I doubt you squeeze that much out of half a lime, which is what this recipe calls for, so you’re good on carbs there.


We used plain old clear Bacardi for this recipe. I would stay away from super high-quality rums because those aren’t for mixing (I’m a bit of a rum snob). Also, a spiced rum isn’t really necessary. You want the blackberry and mint flavor to shine through in this drink.

Blackberry Bubbly:

You can use a bit of seltzer water if you don’t have this on hand. Blackberry Bubbly just reinforces the flavor of the blackberry without adding any carbs or funny ingredients.

Also, if you like flavored water, this stuff is quite good all on its own! You can get this for the same price at Walmart or Amazon, so it’s easy to get your hands on.

Here is the Amazon link because why not get it shipped to you?!


Mortar and Pestle

The only special tool I would recommend here is a mortar and pestle.

You can muddle the mint in other ways, but every kitchen needs a mortar and pestle for smashing up spices and mixing various ingredients.

It’s one of those old school kitchen tools I thought I would never need until I got one. Now I find myself using it fairly often.

If you buy one, get one that’s good and heavy like the one I’ve linked here.

Method Notes

Don’t get in a hurry. There are a lot of “quick” mojito recipes out there, but if you really want the flavor to come out in this one, take your time and do it right. Your patience will be rewarded.

It’s a good idea to make the “blackberry simple syrup” mixture ahead of time and let is sit in the fridge overnight. I’ve humbly requested that Rebecca go ahead and make up several gallons of the stuff just to have on hand all the time. Because….. we might have company or something.

A few of our readers asked us what we’re using to test our blood for Ketones. We did a bunch of research and found that Keto Mojo (affiliate link) had great reviews. We ordered one and started using it. We’ve been really happy with it, and I have no problem recommending it. It’s far more accurate than the Ketone strips you pee on.

The downside is that the strips themselves are a little pricy, especially if you’re checking your ketones every day. They’re worth it, though, if you want to keep an eye on how certain foods effect your blood and make sure you’re not being knocked out of ketosis by something you’re eating.

Welcome to Keto Ginger; a blog about our journey along the Keto Road. We hope our research, experience, and recipes will help others who have started down the same path, or who are simply Keto curious.
