Rockfish - a bar located in Ginza, Japan that's known for their highballs (more than 90% of their orders are for this Whisky soda cocktail), including their signature "kaku" mixture served without ice in a glass straight from the freezer.
RONIN has its own spin on the Rockfish highball using Kakubin Premium Whisky and a frozen Ishizuka glass.
50 ml Frozen Kakubin Premium Whisky
1 Lemon Peel
190 ml Bottle Wilkinson Soda Water
1. Pour 50 ml frozen Kakubin premium into a frozen collins glass (RONIN uses Ishizuka tumblers)
2. Twist one lemon peel to release oils and drop inside
3. Empty the contents of 1 bottle Wilkinson Soda Water into the glass
