Don't stop reading if you've never canned anything. You can always make the syrup and store it in the fridge. And if you're brave enough to buy some jars at a hardware store, it's way easier than you probably think. Let's start with the syrup:
Rhubarb Simple Syrup
3 parts rhubarb, cleaned and chopped
3 parts water
2 parts sugar
Cut off the ends of the rhubarb (but do not "string it", you want the red outer layer to make it pretty and pink), clean off any visible dirt and chop into 1/2 to 1 inch pieces. Measure. Use the ratio above to figure out how much water and sugar you need by volume. I had about 3.5 cups rhubarb, which once processed, made enough syrup for these two pint jars and enough left over for me to have a cocktail or two tonight. yay me!
Throw everything in a saucepan and bring to a boil. Reduce to simmer and cook for 15 minutes. The rhubarb will be super mushy and the water should be pinkish. Don't mash up the rhubarb more than necessary, as you don't want a cloudy syrup. Let drain into a bowl through a fine-mesh strainer, but let it drip on its own, don't press. You can stop here, or if you want to can it, set the bowl contents aside while you get your jars ready.
Canning 101
Bring a big pot of water to a low boil. Make sure before you start that the height of the water is taller than your jars! Gently lower your clean jars into the water and throw in the lids. Sterilize jars for 10 minutes (you can do this while the syrup's cooking if you were smart and read ahead).
While your jars are heating, warm up your syrup (transfer it back from the bowl to the original pan and heat it up). After 10 minutes, remove the jars using tongs, carefully tipping upside down to get the water out. Use the tongs or one of those fun magnet things that come with a canning kit to retrieve the lids.
Carefully pour hot syrup into hot jars and fill to 1/2" from the top. Wipe any stray syrup from the lip of the jar with a clean towel and put lid on top. Screw on canning rings and twist until snug (do not force). If you have extra syrup that won't fill a jar, store it in a container in the fridge and use it up over the next couple weeks. All that sugar should preserve it pretty well.
Gently lower your jars back into the boiling water. You might want to use the handy jar lifter tool that comes with a canning kit. Once water returns to a boil, turn down the heat a bit so that it isn't boiling too hard but is still boiling, and set timer for 10 minutes. Make sure the jars don't touch each other and that the bubbles don't make them bounce around (you don't want them to break). I don't use a rack, but a real canning set up will include one to hold your jars and make getting them in and out of the water a lot easier.
After 10 minutes, lift the jars out of the water with your jar lifter, and let cool on the counter for 12-24 hours. In the next few minutes you will probably hear a "pop" as the lid forms a seal. Check the lids after they're cool by removing the ring, lift up on the lid to see if it will come off. If not, it's sealed. Store in pantry until your next party or summer cocktail craving.
What do I do with Rhubarb Syrup?
You can make a refreshing summer drink by putting an ounce or two into a glass of cold seltzer.
Or, to make a basic fizzy cocktail, add a shot of rum or vodka.
Or, skip the seltzer, shake 2 ounces syrup with 1 ounce vodka/rum/tequila and juice of one lime, strain and you've got a cosmopolitan/daiquiri/margarita.
