For the apple cinnamon infused whiskey:
  • 1 whole apple of choice, cut into chunks (we used McIntosh)
  • 5 whole  cinnamon sticks
  • 16 ounces whiskey of choice (we used Maker’s Mark)
For the Spiced Simple Syrup (makes 16 ounces of prepared simple syrup):
For the cocktail:
  • 1 tbsp prepared sugar free cranberry sauce (we omitted the cinnamon and vanilla extract for this application)
  • 2 ounces apple cinnamon infused whiskey (could sub for regular whiskey)
  • 1 tbsp* Spiced simple syrup, to taste (we recommend using about 1 tablespoon to start and then adjust from there, see notes)
  • 1 dash Angostura bitters
  • Garnish with orange peel, cranberries, rosemary sprig (your choice)
To make the apple cinnamon infused whiskey:
  1. If you are going to infuse your whiskey, you will need to do so a few days ahead of time. Simply add your apple chunks and cinnamon sticks to some whiskey, cover and shake for about 30 seconds, then let it sit for about 3-4 days (or longer). Let the infusing whiskey sit in a cool and dark place. When you’re ready to use it, strain the whiskey and discard the apple chunks and cinnamon sticks. Your whiskey will keep for a long while in the fridge.

To make the spiced simple syrup & cranberry sauce:
  1. When it comes time to making your drink, you want to start with making your spiced simple syrup and cranberry sauce first. Both are extremely simple to make but they should cool down a bit before being handled. Here's the full instructions on how to make the low carb cranberry sauce.  

  2. To make the simple syrup, in a sauce pan, add your spices and toast until fragrant. Then, add your water and let the spices and the water come to a rolling boil. Allow the spices and the water to boil together for 15 minutes. The reason we do this is to get a very strong spice flavor infused into the water.

  3. After the water turns a nice golden brown, it’s ready. Simply remove and discard the spices, and then add your sweetener until it dissolves. You can stir with a spoon to help it along. You do want the water to be quite hot while adding the sweetener. Set aside for it to cool down. That’s it!

To make the cocktail:
  1. Fill two rocks glasses with ice. Spoon in the low carb cranberry sauce to taste, we used about a tablespoon.

  2. Add in some spiced simple syrup to taste. Add a small amount first, then adjust once you put the cocktail together to make sure that the sweetness level is to your liking.

  3. Now, simply add in your apple cinnamon infused whiskey, a dash of angostura bitters and then stir! Taste, then adjust sweeteners if you want.

  4. Now, simply garnish with cranberries, and orange peel and a rosemary sprig if you want.

  5. Enjoy!
