So does that not supply you with used grounds? We generally get through a pot a day, and that supplies us nicely!
There’s no shortage of curries in France, you just need to look a bit harder.
I’m not motivated for the drying task. Every now and then, however, I do let ou plants and flowers benefit from a few cups of espresso grounds.
I don’t bother drying them and just throw them into plant pots etc as mulch.
I am back in Lyon in the winter and booked a hotel not far from a curry house
