This is a typical Thai dessert. Choose bananas that are not too ripe as they need to hold their shape after cooking. This simple dessert is traditionally eaten warm, and sometimes as a snack. Remember to treat coconut milk as you would fresh milk or cream and refrigerate any that is left over. The addition of salt is important as it balances the sweetness of the sauce with the richness of the coconut milk.
