Scald the 3/4 cup cream with the milk in the top of a double boiler over direct heat. Add the sugar & salt. Pour a small amount of the milk mixture into the beaten yolks. Add the yolks to the milk mixture & over simmering water cook until thickened to a custard consistency (coating the back of a spoon.) Remove from the heat & cool. Mix the mashed fruit with the remaining 4 cups cream. Blend into the cooled custard.
If using a manual freezer, fill container 3/4 full. Pack ice & rock salt around the edges, using 3 parts ice to 1 part salt. When the crank gets too hard to turn & the ingredients have solidified to a soft ice cream stage, remove the dasher & pack down the ice cream. Repack fresh ice & salt around the sides, wrap in burlap or newspaper & let stand 1 hour. Freeze in paper cartons. For an electric ice cream freezer, foll the manufacturer's directions.~~

I adjusted this recipe because I only had regular coconut milk in the house which is very rich, so thinned it with another cup of 2% milk and added more sugar and rum accordingly. It's nice with fruit spooned over it.
