Doombuggy Productions specializes in producing guides for DIY homages to Disneyland—in particular The Haunted Mansion. But their Adventureland section has some nice things for Enchanted Tiki Room lovers too.
The site has recipes of simulations of the Tiki Room queue favorite Dole Whip, as well as reproductions of entries and beverages from the now defunct Tahitian Terrace and the soon to be closed (or so the rumor goes) Bengal Barbecue.
UPDATE: Doombuggy Productions website is now offline, but some of the articles have been archived at JimHillMedia.com, including many of the Adventureland recipes.
UPDATE 2: The recipe for the Dole Whip was conspicuously absent from the link above, so I grabbed it from a cached version of the site using the Internet Wayback Machine. Enjoy!
Ice Cream Maker
1 quart pineapple juice (Dole)
1 tsp vanilla
3 cups cream
3 cups sugar
1. Mix the pineapple juice and sugar...make sure that the sugar is dissolved.
2. Next add the cream and vanilla.
3. Poor the whole mixture into the Ice Cream container.
4. Add milk to finish filling to the "fill line"
At this point simply follow the instructions on your ice cream maker.
When the ice cream is ready you can serve it as is or you can stick it in the freezer for a while and let it set up a bit.
