Ginger Lime Shrub

Cut 6 limes in half. Squeeze and reserve the juice in one bowl, and reserve the rinds separately.

Weigh the rinds in a bowl, then added an equal weight of sugar to them. After muddling the sugar and rinds for a bit, cover the bowl and place it in the refrigerator overnight.

After a day or so, a thick syrup should have formed from the rinds and sugar.

To the rind/sugar/syrup, add the reserved lime juice. Also, add ~3 tablespoons of grated fresh ginger. 

Let the mixture sit at room temperature for a couple of hours, then strain the liquid from the rinds. 

Finally, add the apple cider vinegar to the mixture and stir until the sugar is completely dissolved. Note: you can add a tablespoon of the vinegar at a time, tasting the syrup after each addition (the total amount depends on your taste preference for tart vs. sweet).

Pour this mixture into a sterilized bottle, and shake well. Store in the fridge, shaking well before each use.
