Rhubarb and mint shrub
230gm rhubarb, finely sliced
12 mint leaves
400gm white granulated sugar
360ml apple cider vinegar
Notes
The mint can be replaced with basil leaves. The general accepted starting point for a shrub is a 1:1:1 ratio: equal parts of sugar, fruit and vinegar. Omit the vinegar and add a little to the glass when pouring.
