If you prefer a stronger drink, then simply double your vodka amount to a total of 2 ounces. Differentiating amounts of grenadine will play a huge part in the color, so do not be afraid to get your shade of red just right. This recipe serves very well in a summer party punch bowl, especially if you fill the bowl with some cherries, lemons, and limes. Garnish with fresh lime slices and a maraschino cherry. To quickly chill the drink, place all ingredients in a cocktail shaker and shake vigorously. Pour into a glass and garnish.
