Put xylitol in a small saucepan, add the water carefully and simmer.
When the xylitol has dissolved completely, take off the heat.Pour the syrup into a blender glass or a blend resistant container. Let the syrup cool down a little before adding the xanthan gum (this is to prevent clumping).
Add the xantan gum and blend until the xantan is evenly distributed (I use the accessories to whip cream with a hand mixer). The syrup will likely get a cloudy look but without noticeable chunks of xantan gum.
Put in a clean, airtight container and let it rest for 24 hours at room temperature. After that, store it in the fridge and use within a month.
Notes:
Sugar free xylitol may be stored in a airtight, sterile and closed container for up to 1 month in the fridge.
You can also freeze sugar-free simple syrup.
