To make 1 Jack-O-Lantern, you will need:
50ml whiskey (Jack Daniels to make the name even more relevant!)
50ml orange juice
Drop of Grenadine
Ginger ale to top
Orange and lime or cucumber to garnish
Shake the Cointreau, whiskey and orange juice over ice. Strain into a short glass. Stir in a drop of grenadine to achieve an orange hue. Top with ginger ale. Slice an orange at it's largest part. Trim some lime rind or cucumber peel and twist into the orange to make your pumpkin stalk. Gently gloat the orange on the top.
