Maybe I'm silly, but I can't find the way to give the person their pickle jar?
Yeah unfortunately we didn't really manage to put together a tutorial just yet but maybe it's because you forgot to put brine in the pickle jar? After you take the delicious pickles out of the pot you touch it with a brine (like the chili or salt), the jar changes colour and the victim I MEAN CUSTOMER will happily take it off your hands ;D
