"A mixture of pineapple and coconut with a slight hint of rum flavoring makes this non-alcoholic ice cream a big hit on a hot summer day. I made this recipe up, but I think it's the best ice cream I've ever tasted. But be forewarned - it's very rich! Leftover ice cream keeps very well."
Combine pineapple, condensed milk, cream of coconut, flaked coconut, and rum flavoring in a large bowl. Pour into an ice cream maker. Pour in enough milk to reach the freezer line of the ice cream maker.
Freeze ice cream according to manufacturer's instructions. Transfer canister to the freezer and freeze until ice cream is firm, 2 to 4 hours.
