Add the blueberries to a medium sized pan, with the water and honey.
2 Cups Blueberries, ¼ Cup Honey, ¾ Cup Water
Bring to a boil and then reduce to simmer for 10 minutes.
Strain the blueberries through a sieve and the remaining syrup can be placed into a decanter and refrigerated until desired.
Add ¼ cup of the syrup to 1 Cup of Milk.
3 Cups Milk
Storage Instructions
Store the syrup in an airtight container in the refrigerator for up to 4 days. It also freezes well (just the blueberry syrup). Add the syrup to an ice cube tray, freeze, then remove the syrup cubes and put into a freezer safe ziplok bag and pull them out when you need to.
Notes
I used honey in this recipe as I like to avoid sugar where possible. If you prefer your milk drink sweeter feel free to add sugar to the blueberries when cooking down.
