Options for Canning Blueberries without Sugar
The sugar in this recipe is not needed for safety, as you can preserve blueberries in just water. So you have the flexibility to explore alternative sweeteners to customize the flavors according to your preferences! Here are a few options:

  • Honey: Substitute some or all of the sugar with honey for a natural and distinct sweetness. Keep in mind that honey has a stronger flavor, so it may impact the overall taste of the blueberries.
  • Maple Syrup: Replace the sugar with maple syrup to impart a rich, earthy sweetness to the blueberries. Note that maple syrup may add its unique flavor profile to the final product.
  • Stevia: If you're looking for a low-calorie option, you can use stevia as a sugar substitute. Since stevia is much sweeter than sugar, adjust the quantity accordingly to achieve the desired level of sweetness. Note that the taste of stevia after the canning process may change, do a test batch first to see if you will enjoy it before processing an entire batch!
  • Agave Nectar: Another natural sweetener, agave nectar can be used as an alternative to sugar. It offers a mild and slightly fruity flavor that pairs well with blueberries.
