After chopping your rhubarb & strawberries, add to a large jar or glass bowl.

Next, pour in 1 cup of white sugar and mix. You can gently mash the fruit as well, with a wooden spoon or muddler.

Close the jar (or, plastic wrap the bowl, if using) and place in the refrigerator to chill for 2-3 days. The sugar & fruit will macerate over this time, and a syrupy juice will be the result. Try to mix 1-2 times a day to make sure the sugar fully dissolves.

After 48 hours or so, take your mixture, and strain the contents through a sieve over a large bowl. Mash the fruit remains gently to get as much liquid out as possible (you can keep these bits to eat in yogurt if you like!).

Using only the liquid, add 1 cup of vinegar and mix. Return the shrub to a large jar with tight-fitting cover. Let chill for at least 8 hours, and you now have a tasty shrub!

Add to your favorite cocktail straight, or combine 1 ounce to every 8 ounces of club soda for a refreshing soft drink.

This mix will stay good in your refrigerator for at least 6 months.
