Traveling with a cocktail is a bit tricky, what with open-beverage laws and such. However, a lovely flask cocktail can certainly grease the social wheels on such occasions as summer picnics, sporting events, bonfires, or your in-laws’ backyard barbecue. Even though this cocktail hour idea may not help you on an airplane, these flasks and accouterments work well for outings like festivals, or whenever you might desire a sip of a tasty cocktail on the go.
Mixing a cocktail for a flask requires a bit of forethought. First, you should know how much liquid your flask holds. If you’re not sure, you can always fill your flask with water and then pour that liquid into a measuring cup to get an accurate reading of ounces. Most flasks are either 6-ounce or 8-ounce, but sometimes hold slightly less due to the shape. Most classic stirred cocktails (sans citrus), are in the 3-to 4-ounce range, so about two to two and a half cocktails will fit into the flask.
To mix it up a bit, we’re adding ingredients beyond just a single spirit. There are different schools of thought on the kind of cocktails you can put in a flask. Some bartenders are okay putting citrus in a flask, but I think the acid reacts with metal, leaving a metallic taste, so I try to avoid it. Serious Eats and The Times-Picayune of New Orleans have a few recipes they recommend, but this is one that tastes delicious from a flask. It is a riff on the Independent but simplified with ingredients that are easier to find.
1-½ ounces blended Scotch whiskey
½ ounce Cointreau
½ ounce Punt e Mes (sweet vermouth)
½ ounce Cocchi Americano
2 dashes orange bitters
Add all ingredients into a mixing glass.
Carefully pour into flask.
This makes 3 ounces of liquid, so it can be doubled for a 6-ounce flask.
