Doubt I'll be doing this audax but just to add a voice to the side of reason, I love rice pudding, it's awesome, and I wouldn't not cook it just cos some philistines don't like it.
It is one of the foods that can be eaten when the digestive system is under stress as it sometimes is on an audax.
I'll grant you coconut sounds a bit weird though, stick to plain. Serve hot, preferably straight out a bubbling vat, and and have loads of strawberry jam with it.
