Fruit shrubs like this strawberry rhubarb shrub are both trendy and historic. A mix of fruit, sugar and vinegar it can be used for cocktails or soft drinks.
Combine the cut up strawberries, rhubarb and sugar. Mix together until all the fruit is coated with sugar. Let sit for 1 hour at room temperature.
Mash the fruit to break it up, then let it sit for another hour. At this point, a lot of the juices should have been released.
Mash the fruit again until it is very mushy. Let sit, covered, at room temperature, for 24 hours.
Add in the vinegar, stir, and let sit, covered, for one week, making sure to give it a good stir every day.
After a week, strain the fruit from the mixture and save the liquid in a mason jar for up to 3 weeks.
Notes
I started out using the apple cider vinegar recommended by the creator, but ended up preferring white wine vinegar since it didn't dull the bright colors of the fruit.
