    To prepare this sugar free simple syrup, grab a small saucepan, and a few ingredients. This syrup will keep in the fridge in an airtight container for about a week. Mix it into everything to add lots of raspberry flavor, without adding tons of extra calories or sugar.

    We've included some helpful tips about preparing this raspberry simple syrup in the body of this text. Make sure to read through if you have questions, because we probably answered them. You can always skip straight to the recipe card to get right into it.

    Ingredients:​

    • Fresh raspberries - For the raspberries, fresh work really well, but you could also use frozen raspberries instead.
    • Allulose - Allulose is the sugar replacement, and the base for so many of our sugar free simple syrup creations. It tastes like sugar, measures like sugar, caramelizes like sugar, and it won't crystallize after refrigerating it unlike other sweeteners. There are a few things to watch out for when using allulose. We'll discuss tips for using allulose in more detail further on in the post.
    • Water - Can't make simple syrup without water, this is pretty straightforward!
    • Lemon juice - This part is optional, but fresh lemon juice helps increase the shelf life of your raspberry simple syrup! Lemon juice helps to keep mold from growing, since it kills bacteria. We use just a small amount, so it doesn't contribute to the flavor.

    How To Make A Sugar Free Simple Syrup:

    To make simple syrup, whether with real sugar or a sugar replacement, it's very easy! You combine equal parts hot water and sugar free sweetener of choice and stir until it dissolves. Some sweeteners will crystallize once they are cold (ie. In the fridge), but you can remedy this by warming it up prior to using it.

    Allulose sweetener is our preferred method for the texture and flavor. Allulose acts just like sugar, tastes like it, and it won't crystallize when cold. Allulose is ever so slightly less sweet than regular sugar. Use about 1 and ⅓ cups allulose to every 1 cup of water.

    A warning you should note: we have personally found that using too much allulose it upsets our stomach pretty badly. If using just a small amount, like what you would find in this cocktail, you will be be just fine. If you have a sensitivity to allulose, it’s definitely something to be aware of. In other words, if you plan to drink about four of these cocktails, be aware!

    How To Make Sugar Free Raspberry Simple Syrup:

    Add raspberries, water, allulose and lemon juice to a small sauce pan. Heat on the stovetop over medium high heat, until the water starts to boil. Reduce the heat, and bring to a simmer for about 10 minutes, until raspberries soften significantly.

    After the raspberries are nice and soft, remove from the heat. Strain into a clean glass jar or container using a fine mesh strainer. Allow to cool completely before adding to your cocktail or drink of choice, like this Keto Raspberry Moscow Mule.
