To make your pineapple spears, slice off the top and the bottom of the pineapple and remove the skin. Cut the pineapple in to 8 long spears, (cut the pineapple in half length ways, each piece in half again, and then in half again!)
Use your knife to slice the core off of each spear.
Sprinkle the dry sugar mix all over each spear and let them sit for a few minutes on a tray lined with foil.
For your basting glaze, melt your butter in a small saucepan, add the brown sugar and cinnamon and heat through, stirring until the sugar is properly melted.
Fire up the grill to medium heat.
Place the pineapple spears on the grill and baste with the glaze. Continue to turn and baste every minute or two.
Grill for about 10 minutes or until it’s as brown and caramelized as you like it.
Remove from heat, plate it and drizzle any remaining glaze over the top!
