Different people have different choices of cream. You can use half and half, full cream, coconut cream, evaporated milk, or sweetened condensed milk as your choice of creamer. I am a big fan of using condensed milk in my Thai Tea as it gives it a very earthy kind of sweetness and a creamy texture to the tea and I have seen most vendors using condensed milk as their choice of creamer too. But if you are looking for a low cal option, try using low-fat milk instead.
