Cocktail hour in our household is at 6. Just about every night - not when we are going out to a dance.
We have cheese (usually two types) and crackers (two types). Occasionally also smoked mussels, paté or something else such as octopus.
For drinks there is huge variety: single malt scotch, rusty nails, sherry, dubonnet, bloody mary's, martini's, pisco sours. Just one small deink. Robert is the usual preparer - I occasionally do simple things like sherry or scotch and I make the pisco sours.
Pisco sours: 1 oz simple syrup, 2 oz limejuice, 4 oz pisco, 1 egg white; shake in cocktail shaker with ice, pour into glasses and top with a few drops of Angostura bitters. Learned about this drink in our several trips to Peru. Pisco is kind of a Peruvian brandy.
