Ingredient Substitutes for Rhubarb Syrup

If you’re looking to make a healthier version of rhubarb syrup, or if you’re trying to avoid using sugar, there are several ingredients that you can use as substitutes. Just keep in mind that the amount of sweetener you use will depend on your personal taste preferences. Start with a small amount and add more as needed.

  • Honey: Honey is a natural sweetener that can be used in place of sugar in many recipes, including rhubarb syrup. Keep in mind that honey has a distinct flavor that may alter the taste of the syrup.
  • Maple syrup: Maple syrup is another natural sweetener that can be used as a substitute for sugar in rhubarb syrup. It has a rich, sweet flavor that pairs well with the tartness of the rhubarb.
  • Stevia: Stevia is a natural, calorie-free sweetener that can be used in place of sugar in many recipes, including rhubarb syrup. Keep in mind that stevia has a slightly different taste than sugar, so you may need to adjust the recipe accordingly.
  • Agave nectar: Agave nectar is a natural sweetener that can be used as a substitute for sugar in rhubarb syrup. It has a mild, sweet flavor that won’t overpower the taste of the rhubarb.
  • Fruit juice: You can also use fruit juice, such as apple or orange juice, to sweeten rhubarb syrup. Just be aware that this will change the flavor of the syrup and make it less tart.

You can also try adding other fruits with the rhubarb when you make this recipe. Strawberries or blueberries would be delicious and give a slightly different flavor variation.

Frequently Asked

What is rhubarb syrup made of?

Rhubarb syrup is a simple syrup made of just three ingredients, rhubarb, granulated sugar and water. You can substitute the sugar for honey if you choose.

What is the shelf life of rhubarb syrup?

The shelf life of rhubarb syrup can vary depending on how it was made and how it is stored. Generally, homemade rhubarb syrup can last for up to 2 weeks when stored in an airtight container in the refrigerator. However, if the syrup is not stored properly or if it becomes contaminated, it may spoil more quickly.
To extend the shelf life of your rhubarb syrup, you can add a small amount of vodka or other high-proof alcohol to the syrup. This will help to preserve the syrup and prevent it from spoiling. Just be sure to label the container clearly if you do this, especially if you plan to use the syrup in recipes that will be served to children or people who do not consume alcohol.
If you notice any signs of spoilage, such as mold, an off odor, or a change in color or texture, do not consume the syrup and discard it immediately.
