Smashes

Dissolve 1 lump of sugar
Add 4 leaves of green mint, and crush mint and sugar very lightly together
Place lump of ice in glass
Then add one small glass of either Bacardi rum, brandy, gin, Irish whiskey, or Scotch whiskey as fancy dictates.
Decorate with a slice of orange, and squeeze lemon peel on top.
