Shrub & Tonic

1/2 cup blueberries

Sugar

Bunch of Lemon Balm

Apple Cider Vinegar

---

In a glass jar mash blueberries then add enough sugar to cover them. Stir the blueberry and sugar mixture and add more sugar if needed to ensure they are covered. Cover with a lid and place in the fridge.

In another glass jar add lemon balm and cover with apple cider vinegar. Cover with a lid and leave on the counter.

Let sit 1-3 days, occasionally stirring blueberry mixture and shaking vinegar jar.

Do a final stir on blueberry mixture which should now be mostly liquid. Strain out liquid into a clean jar. 

Strain vinegar from lemon balm. Combine 2 parts blueberry sugar and 1 part vinegar and shake well. 

Notes: Adjust the amount of vinegar to taste. Mint can be used if lemon balm is not available.
