Fill a highball glass with ice. A crystal glass most assuredly improves the taste

Add the Gin. This is the element that requires extensive research. My personal favourite is Bombay Sapphire which has an herbaceous and complex flavour but I would encourage you to sample as many types as possible. Just like a good scotch or wine there are many flavour combinations. Gordons is really light and crisp, it isn’t very complex or herbaceous. Tanqueray is quite lemony and a bit sharper and more bitter. Plymouth Gin is full bodies with strong juniper overtones. The amount required traditionally is 30ml but I have found that it sometimes depends on how much positive outlook you require. Once again this also takes some research to get it right.

Add the tonic.The correct proportion is one measure of gin and two of tonic. Again, significant research is required.

Garnish with a slice of lemon lime to finish it off, I prefer lime with my Bombay gin but if I can’t get it then lemon. I use lemon with Tanqueray or Gordons.

Use fresh tonic water from a small bottle or can. Do yourself a favour and don’t get the diet style, after all this is for medicinal purposes

Take your refreshment out to the porch and consume till your positive outlook on life has been restored.
