Tbh confused how you even managed to burn the coffe with this, as it is just evaporating water that filters through the coffee above - like did you put the coffee in the bottom part? 🤔
I haven’t experienced this, but from what I hear if you start with cooler water in the bottom and have the heat set too high, you can overheat the pot and the grounds before the water comes to temp to actually brew.
The few times I’ve used my moka pot I’ve preheated the water in a kettle so it gets to brewing faster (based on coffee people recommendations online.)
