It seems like a random thing to do (dip a whole chilli into your glass) but this is actually an amazing drink! The chilli gives the drink a subtle kick which cuts through the sweetness of the pineapple. Yum yum. Highly recommended (especially for chilli lovers).
One whole red chilli
Slice into the chilli and scrape out all the seeds
Put ice cubes and a decent splash of pineapple juice in the botton of your glass
Top up with soda water
Add the chilli
