My moka pot is sputtering coffee instead of pouring flowing coffee so I'm trying to find a solution on how to fix this. I stumbled upon this video, with a similar issue in which the filter is a bit loose so the heated gas doesn't transfer properly. His solution was to use some PFTE tape on the filter to make it tighter.
My father saw this and said that aluminium foil would work better because it's meant to be put on food. I am no expert and just want to be safe. Are there some hazardous side effects when using aluminium foil?
