Add the lemonade to the glass. You can use the measurements indicated in the recipe card, or simply fill the glass most of the way with the lemonade.
Finish the drink by drizzling the raspberry cordial over the top of the glass. It will sink to the bottom (because it has a greater sugar content than the other ingredients) and make that beautiful layer of color.
Garnish your cocktail with pineapple wedges and skewered raspberries, and serve!
