Take a liquidizer or blender and place some ice cubes.
Now, gently pour 1 shot of fresh lemon juice, ¼ shot of grenadine, 1 shot of whiskey and 4 shots of soda.
Seal the lid of your blender or liquidizer and blend it at medium speed for a few seconds until you feel that all ingredients have mixed well and smooth.
Remove the lid of the blender / liquidizer and carefully pour the drink into a pre-chilled cocktail glass.
Now, garnish your Whiskey Daisy Cocktail with any of your favorite fruit wedge. However, lime or lemon wedges are preferred.
Your Whiskey Daisy Cocktail is all set to go; place a straw in the glass and serve right away.
