I seek a small round tripod ring to keep a pudding bowl off the bottom surface of a pot during steaming. I have two, bought long ago, so I know they exist. Any suggestions?
Not a tripod, but a squat can with top and bottom removed will work - although these days few cans have bottom rims.
Cookie and biscuit cutters of any shape will work as long as they are open on top and have no handles.
Do you have a local asian store? My girlfriend's mom has a bunch of those but not sure they are made to withstand steaming (not sure of the composition of the metal).
