Modak is considered to be the favourite sweet of the Hindudeity, Ganesha. It begets him the moniker modakapriya (one who likes modak) in Sanskrit.
During Ganesh Chaturthi, the puja usually concludes with an offering of 21 modaks to Ganesha as prasad Modaks made with rice flour shells are often preferred for this purpose, although wheat shell versions are also used. Local businesses outside Ganesh Temples across India usually sell pre-packed/readymade versions of Modaks.
In Japan, a sweet similar to modak and known locally as Kangidan (歓喜団), is offered to god Kangiten, the Japanese version of Ganesha. Kangidans are made from curds, honey, and red bean paste. They are wrapped in kneaded dough made from parched flour and shaped like a bun before they are deep fried.
