Drain the crushed pineapple. If you have cheese cloth you could use that or a fine mesh strainer. I squeezed out as much liquid as i could.
Using an electric mixer or a spatula mix all the ingredients together. I started with about 1/4 tsp. rum flavoring and added until I liked the flavor.
Spread on tortillas and roll up. Wrap in plastic wrap and let set at least an hour. Cut in about 1/2 in. slices. Electric knife works well. You could top with a 'shot' of canned whipped cream and a sprinkle of toasted coconut if you want it to look nice. (I did not have time to do that when I served them.
