Spiced Pumpkin Shrub

"Guys, I am seriously obsessed with this drink. I've already had all of it after taking pictures and want to make more! Pumpkin shrubs are perfect on their own or with sparkling water, or with a bit of booze added in (may I recommend brown butter infused whiskey or a maple bourbon?) this is my recipe for the ? virtualpumpkinparty ? and it will be up on the blog Monday!"
