Earlier quoted context omitted.
Chilies are pretty simple to grow yourself, even just by using the seeds from a dried one. A happy plant produces lots of chilies and the freeze fine for most uses. They don't like the cold, though, so depending which part of Germany you're in you might need to keep it indoors (but still with access to a few hours of sun a day).
Planning to do that chili con carne next Sunday, so no time to grow the plants... Also electricity is super expensive in Berlin, so any artificial growing lights will break my monthly budget.
Edit: this place looks promising in Berlin: https://potandpepper.de
