Total Time 15 minutes

Equipment

  • Small Saucepan:
  • Spoon or whisk:
  • Measuring cups
  • Glass jar or bottle with lid (for storage)
  • Fine mesh strainer (optional, if you use add-ins like citrus peel)

Ingredients
  

  • 1 cup water
  • 1 cup granulated sweetener (like erythritol, monk fruit, or allulose)
  • Optional: ½ tsp vanilla extract, 1 cinnamon stick, or a strip of lemon peel for flavor

Instructions
 

  • Step 1) Combine the water and sweetener in a small saucepan. Use equal parts, usually 1 cup of each.
  • Step 2) Heat the mixture over medium-low, stirring frequently. You don't want to boil it. Instead, warm it enough so the sweetener fully dissolves. It commonly takes about 5–7 minutes.
  • Step 3) If you're adding vanilla extract, spices, or citrus peel, drop them in after the sweetener dissolves. Next, let them steep for a few extra minutes, then remove from heat.
  • Step 4) Strain (if needed) and transfer to a clean glass jar or bottle. You want to keep it in the fridge.

Notes

Notes:

Usually, this syrup last about 2 to 3 weeks in the fridge. If you're using allulose, it tends to hold up even longer and stays nice and smooth without crystallizing. But if you see any cloudiness, funky smells, or (worst case) mold, it’s time to let it go.
Between sweeteners, allulose is the easiest to work with. It dissolves quickly and gives you that syrupy texture without the graininess.
On the other hand, Erythritol can be a bit stubborn. It sometimes recrystallizes once cooled. If you're using it, try blending it into a fine powder first or mixing in a dash of liquid stevia to help keep things smooth.
