Scorpion Cocktail

Aptly named, as it has a sting in the tail!  The relative length of the drink, with fresh orange and lemon juice and loads of ice, means it is dangerously 'gluggable'.  But refreshing on a warm, dry, sunny evening.  Per person, you need 2 parts of white rum (i.e. Bacardi), 2 parts of good, freshly-squeezed orange juice, 1 and a half parts of fresh lemon juice, 1 part brandy (preferably good Cognac), 2 teaspoons of Amaretto liqueur (or orgeat syrup, if you happen to have any lying around, as you do), 2-3 drops of Angostura Bitters, sugar syrup, to taste, and slices of orange and lemon.  Shake over ice, then strain into highball glasses filled with broken ice and garnish with the fruit slices.  ***Hic! ***
