Keto Lemon Drop

This Keto Lemon Drop is the perfect way to relax at the end of your day or to enjoy with friends! This keto cocktail pairs perfectly with almost any dish and is sure to wow your guests. I have always loved a Lemon Drop, so I’m super excited to introduce a keto recipe!

Traditionally, a Lemon Drop includes vodka, triple sec, lemon juice and simple syrup. For our keto drink, I have a recipe for sugar free simple syrup (check out my Keto Margarita or Keto Mojito for more ways to use this low carb alternative!) using Liquid Monkfruit to cut the carbs. I also omitted the triple sec for it’s high sugar content and replaced it with lemon flavored soda water, which has no sugar. This makes an amazing keto cocktail that is so simple to prepare!

Ingredients in this keto cocktail

As always, here is a quick overview of the ingredients used in our keto Lemon Drop. For the complete, printable recipe, just scroll to the bottom of the page.

• Vodka- any brand you prefer
• Lemon juice- I used fresh squeezed
• Keto simple syrup- water and liquid monkfruit sweetener
• Lemon soda water- I used my Soda Stream, but you can find this at most grocery stores
• Sugar for the outside of the rim- this is optional, but it adds a nice touch! This Lakanto Erythritol Blend or Besti Alluslose Blend would both work well here

How do you make this keto drink?

This drink is beautifully simple! In a shaker with ice, combine your vodka, lemon juice and keto simple syrup. Shake until very cold. Next, sugar the rim of the cocktail glass, but this is optional. Strain and pour your keto cocktail in your glass. Garnish with a slice of lemon and you’re done!

Homemade sugar free simple syrup

Simple syrup is usually made with sugar, but I have a recipe that fits with a keto diet. By using Liquid Monkfruit Sweetener, you remove the carbs! Monkfruit is very sweet, much sweetener than sugar, so you need a very small amount. One tablespoon per one cup of water is all that’s needed. If you prefer things to be a little less sweet, or if you’re using a different brand, I recommend starting at 1/2 a tablespoon per one cup of water and adjusting as needed. 

Can I use a Erythritol or Swerve for this sugar free simple syrup?

I do not recommend doing so. Erythritol does not dissolve very well, whether in cold or boiling water. This can lead to a gritty texture and an inconsistent taste. If you add xanthan gum to your hot water with your erythritol sweetener, it should prevent the mixture from crystallizing. I personally prefer using the liquid monkfruit for the taste and the ease in my simple syrup.

Can I make this keto simple syrup ahead of time?

Absolutely! This keeps very well. I can only attest to storing it with the liquid monkfruit, not the erythritol and xanthan gum blend, however. Just store in an airtight container (I used a jar) and keep in the fridge. Shake well before using and that’s all there is to it!
