This spooky low-carb cocktail is perfect for Halloween! I used homemade blackberry juice and substituted the commonly used simple syrup with powdered Erythritol added to the blackberry juice. There are other options you can try:
Skip the powdered sweetener in the blackberry juice and make your own simple syrup like in this Spicy Low-Carb Margarita. The only drawback of making simple syrup this way is that it may partially crystallise once it's chilled.
You could use NuNaturals Simple Syrup. Apart from plain simple syrup, it's available in several different flavours such as Ginger Syrup which worked wonderfully in my Keto Ginger & Rhubarb Creamsicles. Just remember to use the recommended amount as too much would make your cocktail way too sweet.
Lastly, you can just use a few drops of stevia. NuNaturals are my favourite as they don't taste bitter.
