Low Carb Whiskey Sour Slush

One of my favorite cocktails is the famous Whisky Sour slush. When I started on this journey of living a low carb lifestyle, it was one of the low carb cocktail recipes that I worked on first. After many iterations, I really feel this is by far, the best low carb drink recipe I’ve created. So I present to you my favorite low carb cocktail, the Whiskey Sour slush. All the flavor without all the sugar and carbs.

For this recipe you’ll need whiskey, fresh lime juice, xylitol (sugar free sweetener), sugar free cherry syrup, a lime (or lemon) slice, and ice cubes.

My all time favorite celebration cocktail, the low carb whiskey sour !

Is a Whiskey Sour low carb?

Wait. Alcohol doesn’t really have carbs?? Well yes and no. FIrst off, you want to watch the stuff you put in to your whiskey slush. Second, alcohol in general can cause a serious stall to your fat loss (if that’s what you are on a low carb or keto diet for). While the alcohol in the whiskey or other cocktail is in your system you won’t burn fat. That isn’t a big problem unless you start having a drink every single day and your metabolism is on the slow side.

I was able to create a whiskey sour slush recipe with only 5 carbs per serving. So it’s not keto in the strict sense.

Not that I have ever done that. Ha !

Low carb and keto friendly, enjoy the whiskey sour slush.

Is whiskey ok on a low carb diet?

I don’t drink a lot but I do like to have a cocktail once in awhile or a glass of wine with dinner. It’s just that I am a wimp when it comes to booze and I am not an “on the rocks” whiskey kind of girl. I prefer something that tastes like Kool-Aid with a little zip if you know what I mean. Of course that’s kicked me in the butt more than once. When drinks taste like that sugar filled drink we had as kids I tend to guzzle them.

Don’t try that at home, kids.

What whiskey do you use for whiskey sour?

A few weeks ago I started working with a company. They make a lot of the alcohol that we buy so I felt good about endorsing them. They sent out a couple of bottles of whiskey and to my great joy and delight one of them was George Dickel Sour Mash Whiskey.

I love that stuff. Well, in a celebratory way with friends. I don’t enjoy drinking by myself and this is definitely a special occasion kind of keto cocktail I like. It’s not a casual kind of cocktail like a margarita is. I love a margarita with friends on a lazy afternoon. Try my Low Carb Margarita when you are in the mood. I was just off of a round of induction and I decided to create a low carb version of a whiskey sour slush. And now this low carb version is one of my favorite cocktails to celebrate with friends and family. Or date night wink wink.

What I love about whiskey is the smoky flavors that they have. When making whiskey sours, the good news is that the flavors of the lemon juice cuts the bite of the alcohol. That means you don’t have to use top shelf whiskey in your whiskey sour recipe. You could even use bourbon in your recipe and make a bourbon slush. The one thing you don’t use that is in the regular recipe is simple syrup. The reason is that it is just sugar and water. Way too many carbs.

So for this low carb version, I love the flavor of fresh lime juice. A lemon wedge not only makes it classy but you can twist it to get a little of the lemon zest for your cocktail.

Low carb whiskey sour slush. So delicious.

The Lowcarb-ology Extra Special Whiskey Sour Slush

Oh my gosh, it was so good that I had to remind myself not to guzzle. Disclaimers… I used the George Dickel Sour Mash Whiskey that the company sent to me in my bourbon slush recipe. This is a product that I use and so I feel comfortable in endorsing it. Use whatever whiskey you prefer.

    Put in a bowl and freeze it. Did not get too solid, stayed very slush worthy. Rave reviews, people thought it was strawberries, not the lime and sugar free cherry juice. Pretty color, mixed with diet 7 up.

    These cocktails look amazing! I can?t wait to try them……
    Can you tell me what brand of water enhancers you use?… I?m not sure if I know what there are… can u buy them at the grocery store?

    1. I use different ones – you can get them at the grocery store or on Amazon through the links in the post (I usually leave links). I use Mio mostly.

    Would this work for a margarita except use an orange water enhancer and tequila? Would be awesome if so!
