You need a large fresh pineapple, some raw brown sugar, whipped cream, and a bottle of dark rum. Don't use OP rum since the taste is overpowering.
To prepare: Slice the top off the pineapple. Remove the pineapple flesh without destroying the skin (the empty shell is used for display later). Chop the pineapple into bite-sized cubes, place in a bowl and pour on the rum (all of it). Marinate overnight (at least four hours).
When ready to serve: Place separate bowls of the sugar and cream, for your guests to use, and have pre-soaked wooden satay sticks ready. Drain the juice off into a separate container. Put some methylated spirits into a tin can, and place in the shell (if you kept it). Place on table and light. Serve the pineapple/rum chunks. Skewer a chunk, roll it in the sugar, and hold over the flame until it goes toffee-like. Dip in the cream, and crunch. I promise, it's sensational! (With many guests, you may need more than one flame.) When the pineapple is finished, get the jar of juice you saved and serve as an after dinner drink
