Very interesting and yummy drink to have, taste of lemonade with addition of soda gives more refreshing touch to it...
water 2 cups
sugar 1 cup
lemon juice 1/2 cup
salt 1/4 tsp
blue food color few drops
white soft drink
first make sugar syrup with water and sugar and salt, cook until sugar is all dissolved...
let the syrup cool completely, add lemon juice... freshly squeezed is preferable... but i used bottled.... add blue color and mix and adjust color
now, in glass add this blue lemon syrup and equal amount of white drink, add ice cubes or may be slice of lemon and serve chilled
