• Quick: It takes 5 minutes to make this sugar-free classic simple syrup recipe, then just allow it to cool.

🗝️Key Ingredients & Substitutions

• Sugar substitute: You will need to use sugar-free sweetener for this recipe. I’ve made instructions for allulose, erythritol, and xylitol for this post. They’re all a little different. Allulose is the easiest to use as it doesn’t tend to crystalize, but xylitol and erythritol can also work too. If you’re using granulated monk fruit sweetener or stevia, check the other ingredients as they tend to either be mostly erythritol or allulose based, so follow the instructions for the main ingredient.
• Liquid sweetener: If you’re using erythritol or xylitol, adding a few drops of liquid stevia or monk fruit is required to bring the sweetness level up. These two sweeteners need to be diluted with more water than allulose to remain in liquid form. This will give you a less sweet syrup without the drops.
• Water: Still water, ideally distilled water as it will give the best results, although I have used tap water and it has worked well for me.
• Xanthan Gum: This key ingredient thickens the liquid to a syrup-like consistency so that it’s just like regular simple syrup. Otherwise, it’s quite thin, more like sweetened water than syrup. You can skip the xanthan gum if you’re not bothered about the consistency.

🥣How to make Sugar Free Simple Syrup

Using erythritol:

1. Begin by mixing the erythritol with the xanthan gum. This minimized lumps later as xanthan gum tends to be a little clumpy.

2. Carefully add the erythritol and xanthan mixture to a small saucepan along with the water and liquid sweetener, and turn on the heat.

3. There is no need to mix it yet, just allow it to heat up and you will see the erythritol beginning to melt.

4. Bring the saucepan up to a boil, and allow it to boil for 1 minute, whisking as it boils. This activates the xanthan gum.

5. Remove the pot from the heat, place a lid on top, and allow the keto simple syrup to cool to room temperature.

Using xylitol:

1. Begin by mixing the xylitol with the xanthan gum. This minimized lumps later as xanthan gum tends to be a little clumpy.

2. Carefully add the xylitol and xanthan mixture to a small saucepan along with the water and liquid sweetener, and turn on the heat. Try your best to keep the xylitol crystals in the water and not on the sides of the saucepan.

3. Do not mix it, just allow it to heat up and you will see the xylitol beginning to melt.

4. Bring the saucepan up to a boil, cover it with a lid, and allow it to boil for 1 minute. This activates the xanthan gum.

5. Remove the pot from the heat, keep the lid on top, and allow the keto simple syrup to cool to room temperature.

Using allulose:

1. Begin by mixing the allulose with the xanthan gum. This minimized lumps later as xanthan gum tends to be a little clumpy.

2. Add the allulose and xanthan mixture to a small saucepan along with the water, and turn on the heat.

3. Bring the saucepan up to a boil, reduce the heat, and stir it frequently as it simmers for 5 minutes.

4. Remove the pot from the heat, and allow the keto syrup to cool to room temperature.

🫙Storage Instructions

Allow the sugar-free syrup to cool completely before storing. All 3 versions of this recipe should be stored in an airtight container like a jar.

• Erythritol: Store at room temperature for up to 2 weeks.
• Xylitol and Allulose: Store in the fridge for up to 2 weeks.

Ratios for different sweeteners

This is a handy key for the ratios of water to sweetener:

• Xylitol and erythritol: 1 part sweetener to 2 parts water (1:2).
• Allulose: Equal parts water and sweetener (1:1).

🪄Recipe Notes & Tips

• Pet safety: Xylitol is not safe for dogs so keep this away from your furry friends! There isn’t enough evidence to tell whether or not it’s safe for cats or other pets, so it’s best to keep it away from them as well.
• Putting a lid on it: This is an important step for erythritol and xylitol. The lid creates steam within the pot, which will gather any rogue sweetener crystals that are on the sides of the pot and drip them back into the liquid. Why does this matter? If the liquid comes into contact with one piece of granulated sweetener, it will recrystallize leaving you with a gritty syrup.
• Cooling: Allow the syrup to cool naturally to room temperature. Crystallizing can happen if it is cooled too quickly.
• Storing erythritol: Erythritol is a little fragile when it comes to liquid form, and refrigerating it will usually cause crystalization in my experience. Keep it at room temperature for the best results.
• Cloudy color: The sugar free keto simple syrup will most likely have a cloudiness to it and not be crystal clear like regular simple syrup. This is because the xanthan gum makes it a little cloudy. It’s perfectly safe and still delicious!

✨How to make flavored homemade simple syrup

Yes, you can easily make different flavors with this homemade keto simple syrup recipe.

• For bottled flavoring (for example, vanilla essence, orange essence, or maple for maple syrup): After the syrup has cooled, begin by adding 1 teaspoon of flavoring. Mix well and taste it. Add more flavoring as needed, tasting as you go.
• For infusing flavor (for example, cinnamon sticks, allspice, cardamom, lemon zest, fresh ginger, strawberries, blueberries, rosemary, mint): Begin by boiling 1.5 cups of water with 1 cup of fruit, herbs, a couple of cinnamon sticks, and/or 2-3 tablespoons of spices. You will need the extra water as some will evaporate while it boils. Allow it to simmer for 20 minutes and then strain the ingredients with either a slotted spoon or through a strainer. Take care not to press down on any fruit if you want the syrup to remaining clear. Then follow the recipe adding your sweetener of choice and xanthan gum.
