Gin and Tonic

You will need  

1  Lemon wedge
1  Spring of rosemary
2 oz. Hendrick's Gin
4 oz. tonic water
5  Ice and a Shaker

Internet confession. I'm fairly new to making Gin and Tonics but so far this is definitely my favorite way to make it besides garnishing with a slice of cucumber and Im sure itll be yours too

 In a shaker 3/4s filled with ice add Gin  shake until the shaker gets frosty then  strain  over ice  top of with tonic water and garnish with rosemary and a lemon slice .
