A granular erythritol or allulose blend dissolves into hot water to build sweetness without table sugar, while a small amount of xanthan gum and melted butter recreate the body and shine that sugar's viscosity normally provides.

Instructions

  1. 1Combine the water, granular sweetener, and salt in a small saucepan over medium heat.
  2. 2Sprinkle the xanthan gum over the surface a little at a time while whisking constantly, so it doesn't clump into gel-like specks.
  3. 3Bring the mixture to a gentle simmer, whisking often, until the sweetener fully dissolves, about 3 to 4 minutes.
  4. 4Reduce the heat to low, add the butter, and stir until melted and the syrup looks glossy and has thickened slightly, another 3 to 5 minutes.
  5. 5Remove from the heat and stir in the maple extract and vanilla extract.
  6. 6Let the syrup cool for about 10 minutes before serving; it will continue to thicken as it cools. Pour into a jar or bottle for storage.

Tips & variations

  • Erythritol-based blends can recrystallize into a slightly gritty texture once fully cold; allulose-based sweeteners stay smoother and pour more like real maple syrup straight from the fridge.
  • A few drops of butter extract alongside the maple extract deepens the flavor if the syrup tastes flat or one-dimensional.
  • For a darker, more maple-like color, use a brown sugar-style erythritol blend instead of a plain white one.
  • Skip the xanthan gum for a thinner, more pourable syrup meant to be used warm right away rather than stored.

Storage & reheating

Store the cooled syrup in an airtight jar in the refrigerator for up to 2 weeks. It will firm up considerably when cold since there's no sugar to keep it liquid; warm it in 10-15 second bursts in the microwave, or in a small saucepan over low heat, stirring until it loosens back up.

Tips from the Tulo kitchen

  • If the syrup turns cloudy or grainy after chilling, that's the sweetener recrystallizing, not spoilage; gentle reheating with a splash of water and a stir usually smooths it back out.
  • Whisk in the extracts off the heat rather than while simmering, since prolonged heat cooks off some of their aroma.

FAQ

Why does my sugar-free syrup turn grainy in the fridge?

Erythritol-based sweeteners can recrystallize as they cool, giving the syrup a slightly grainy texture. Reheating it gently with a small splash of water and whisking usually restores a smoother consistency.

Can I make this syrup without xanthan gum?

Yes, but it will pour thinner and closer to a simple syrup than a traditional pancake syrup. Xanthan gum is what gives it the clingy, slightly viscous body sugar normally provides.

Which sweetener works best for this syrup?

Allulose-based blends dissolve completely and stay smooth and pourable even cold, while pure erythritol blends are more prone to crystallizing once chilled.

How long does homemade sugar-free syrup keep?

Stored in an airtight jar in the refrigerator, it keeps well for about 2 weeks. Give it a stir or brief reheat if it separates or firms up.
