The riddle refers to asafoetida (heeng). In Daadi's letter, she mentions: 'You know, when you were babies and had gas in your tummy, I used to put heeng (asafoetida) water on your tummy to give you some relief.' The riddle clues 'tummy felt funny' (gas in tummy) and 'used by your granny' point to asafoetida, which grandmothers traditionally use to relieve gas and stomach problems in children.
