Thanks for spotting and bringing to my attention. I believe gaz's original recipe stipulated soda but I found it's better with ginger ale. I've just made soda and ginger ale versions to test and ginger ale wins. Hence, I've amended acordingly above.
Agreed! I've amended [16/Dec/20] the recipe above by reducing the gin from 45ml to 30ml and topping with ginger ale in place of soda. I hope gaz would approve.
