Heat huckleberries, sugar, and water together over a medium heat until the mixture is simmering. Simmer for 2-3 minutes.
1 cup huckleberries, ¾ cup sugar, 2 cups water
Strain huckleberries using a fine meshed strainer. Don't mash the berries down, or the liquid will become cloudy.
Allow the simple syrup to cool for at least 30 minutes. You can also speed up this process by adding 1 cup of ice cubes to the hot mixture.
Lemonade
Add huckleberry simple syrup, freshly squeezed lemon juice, remaining water into a pitcher. Stir. Add ice just before serving.
1 cup lemon juice, 4 cups water
Notes
The huckleberry simple syrup can also be used for mixing into cocktails. Once made, allow it to cool, then cover and refrigerate for up to 7 days.
Don't waste the huckleberries you used to make the simple syrup. You can add a few of the huckleberries to the lemonade or you can serve them over vanilla ice cream, add to pancakes, or eat as a snack.
