In my back yard, I have a rhubarb plant that is originally from our family farm in northern Minnesota. It's over 90 years old and I just transplanted it a few years ago. I wasn't sure it would make it but it just loves the new location. Getting as far south as Massachusetts probably seems like retiring to Florida for this plant, and at that age you deserve it.
Anyway, it produces a lot of rhubarb each year so I'm always looking for new ways to use it. There's rhubarb pie and rhubarb cobbler...but that's really it. Rhubarb is similar to cranberries in that it's really too sour for human consumption until you add a bunch of sugar to it. And, in this case, booze.
But the result is delicious! Faintly reminds me of those Sour Patch candies from my youth, but this is real food (generously defined). I can scarcely think of a better fate for an ancient stalk of rhubarb.
Add strawberries and lemon juice to a cocktail shaker and vigorously muddle to break down strawberries
Add all additional ingredients and ice to shaker, shake
Fill a rocks glass with ice, strain cocktail through a fine mesh sieve into glass. Top with soda water. Garnish with a sliced strawberry
Combine all ingredients in a small saucepan over moderate heat
Bring to boil, then reduce to a low simmer
Cover and simmer ~1 hour, stirring occasionally, until syrup is bright pink and coats the back of a spoon
Strain, discard rhubarb stalks, and store in an airtight container in the fridge for up to two weeks
