Elderflower Cocktail

It's about 0 degrees here and I'm posting summer cocktails. What can I say? We're not intimidated by some cold here in Colorado.  I had tried this cocktail at a party over the summer, and I wanted to give it a try, weather be damned. Traditionally, it's made with St-Germain liqueur. That's some expensive hooch. It's a French liqueur infused with elderflowers, giving it a delicate floral bouquet. I wasn't up to forking over $35 for a bottle, so I settled for the elderflower syrup from IKEA. Significantly cheaper. The Swedes love this stuff. They use it to make an elderflower lemonade (so my Swedish friend Anette tells me). It's much sweeter than the liqueur and it contains no alcohol. Still made for a delicious cocktail, one quite light on alcohol. I've dubbed it the Hummingbird Moth Cocktail. The hummingbird moth, a large moth common in Boulder gardens, is often mistaken for a hummingbird.
