Make sure the tea you buy is herbal and pretty much only has hibiscus and raspberry in it. And hibiscus is the first ingredient.

Put all the ingredients into a pot and bring to a simmer, stirring often until the sugar dissolves. Turn to low and simmer very lightly for an hour. Remove teabags and continue to simmer until the liquid is about 1 cup in volume. This took about another hour. When it is ready, squeeze in the lemon juice and stir. Pour into a container and put in the fridge.

Put a shot of gin into a mason jar filled with ice. Add about 2 tablespoons of your grenadine, but it's up to your personal taste. Stir well and pour in the soda water. Stir and serve with some mint.
