Honey pepper vodka
Horilka pertsivka, or vodka flavored with honey and red chili peppers, is all the rage in Ukraine right now. And while infused vodka is hardly anything revolutionary, this infusion predates hipsters and their crazy craft cocktails by about a hundred years. It's strong, spicy, and usually served with pickled veggies. Hopefully, in a Bloody Mary.
If you've ever tried salty licorice in Scandinavia or Holland, then you'll know what to expect from Koskenkorva Salmiakki. It's a liqueur made from ammonium chloride (the same ingredient in the candy, which is also in cough syrup!) that tastes tart and -- although at least sweeter than the actual salty licorice -- is reminiscent of childhood influenza. The Finnish order it as a shot or over ice.
