Sweetcorn surprise

Variations of this sweet soup - che - are sold on the streets of Vietnam, in special che cafes, and in restaurants. This is my interpretation of the one we ate looking out to sea from the last emperor’s villas; it’s the kind of sweet comfort food I find hard to resist. I use the extra-sweet type of frozen sweetcorn. Glutinous (or sticky) rice flour and coconut milk powder are obtainable from oriental food stores.
