A simple, lightly fermented sweet blueberry syrup for cocktails ice cream or pancakes using the natural water of the fruit, sugar, and aromatics. Makes about 4 cups.
Mix all ingredients and spoon into a half-gallon mason jar or similarly sized, non-reactive container.
Mash the berries and sugar with a mallet or with a gloved hand until the juice has released enough for liquid to slosh around freely in the jar.
Cover the jar with a lid and allow to ferment for 4-5 days, and up to a week.
Cooking the syrup
Scrape the mashed fruit and sugar slush into a pot and bring to a simmer. Once the mixture is bubbling foam may rise to the surface-don’t worry it will dissipate as the syrup cools.
Simmer the syrup for about 10-15 minutes on medium heat. This is not supposed to be a thick-molasses like syrup, but a thin one with a sugar content similar to simple syrup.
Strain the syrup to remove the solids. You can save the cooked blueberries and add them to jam, or mix them with some oats, form into balls and leave them out for birds and squirrels.
If you want to make a chunky syrup with the fruit left in it for using on pancakes, leave the fruit in the syrup.
Canning and storing
Put the syrup back into the pot and bring to a boil. Turn off the heat, beat in the lemon juice and pour the piping hot syrup into jars leaving a half inch of headspace. Process the syrup in a water bath for 10 minutes per pint.
Alternately, you can pour piping hot syrup into jars nearly to the brim, screw on the lids and turn the jars upside down. They’ll seal just like jars of maple syrup.
The finished syrup will keep for months in the fridge if you don’t want to can it and store in a pantry.

Notes
Fermented Huckleberry Syrup
As blueberries and huckleberries are related and interchangeable in recipes, this method can make a good huckleberry syrup recipe too. Evergreen huckleberries are probably my favorite.
