This recipe was created as a part of paid collaboration with Empress 1908 Gin over on Instagram. We weren’t required to make a blog post for the collaboration, but this cocktail was too pretty not to share, so we wanted to make sure you guys got to see it. 🙂

Here’s What We Used For The Summer Herb Gin and Tonic:

  • Empress 1908 Gin, you could use any gin
  • Homemade herbed ice cubes, for fun!
  • Lime slices
  • Homemade basil, sage and mint sugar free simple syrup
  • Diet tonic water
  • Garnish with: fresh basil and sage

What is Empress Gin and Can I Use Any Gin?

As we mentioned, we used Empress 1908 Gin for the gin base in this cocktail. It’s small batch gin made with butterfly pea blossoms that create that lovely indigo hue. It’s fun to experiment with, because it changes colors to a slightly pink-ish color when you add tonic water or citrus. It has a lovely, earthy and botanical flavor, since it’s made with the butterfly pea blossoms, fairmont empress tea, juniper, grapefruit peel, coriander seed, cinnamon bark rose petal and ginger root!

While you can order Empress 1908 Gin online or buy it in stores, but if you’re looking to make this gin with the gin you have on hand, feel free to use your favorite gin.

How Do I Make the Sugar Free Summer Herb Simple Syrup?

We love making all kinds of sugar free simple syrups to elevate our keto cocktails at home. Please note, that this is an optional ingredient, and many people wouldn’t include simple syrup in their gin and tonic. If you’re like us and prefer a drink with a little subtle sweetness and herbaceous flavor, the sugar free simple syrup is a great way to balance out the bitterness of tonic water without adding any calories!

To make the simple syrup, you will need 1 cup of water, and 1.25 cups of allulose. Allulose is our preferred sugar free sweetener for many applications, because it acts and tastes just like sugar. It’s slightly less sweet than sugar, which is why we add a bit more to our simple syrup. For this, we boiled our herbs (we used mint, sage, and fresh basil) in the water for a few minutes to really get that flavor into the syrup. Then, we add the allulose, stir, and let it sit for about 20 minutes before straining away and discarding the used herbs. You will just want to set it aside and let it cool for about 15 minutes or longer so it’s not super hot when you add it to the drink.

Again, the simple is optional, so feel free to skip this step. We’d also like to note you can easily swap out the allulose for regular sugar if you don’t keep track of or think about the extra carbs. Just note that adding the sugar instead will definitely add a lot of calories to this drink. We don’t recommend using any other sweetener for this aside for maybe honey, agave, sugar or allulose. Other sugar free sweeteners will crystallize when they get cold, which doesn’t make for a great texture when you want to use the syrup later. This syrup will keep for an indefinite amount of time in the fridge. We aren’t experts, but we think that as long as it looks and smells fine, it’s probably safe to use. Truly we have used our simple syrups for months after we have made them.

Another fun thing we did to elevate this drink was to make herb infused ice cubes. We simply cut up some mint, sage and basil and froze them inside of an ice cube container to add a little extra flair to the drink.

  • Empress 1908 Gin- This is an optional ingredient, but my is it pretty and has such a lovely taste! Feel free to swap it out for your favorite gin.
  • Limes- You can use any citrus you like, like a slice of grapefruit, lemon, or orange!
  • Diet Tonic Water- You can use whatever tonic you like. We use diet, since we are low carb, but use whatever you want. Sparkling water would also be fine. Just note that the tonic water is what makes the Empress Gin change color, if that’s what you’re going for!

Optional Ingredients:

  • Herb Ice Cubes– These are just for fun and are totally optional. Feel free to just use regular ice.
  • Herbed Sugar Free Simple Syrup– Again, optional, just added to round out the bitterness and add a lovely herbed flavor to the drink.
