I'm looking for a good place/brand to buy pepperoncinis. I've tried various (Unico for instance), but my absolute favourite was one I got from Costco a long time ago. Sadly I don't remember which brand, but I suspect it might be their house brand, and they no longer carry pepperoncini at the various ones I've tried. In general I find the ones in the grocery stores are simply hot, whereas the ones I loved were far more sour and not nearly as spicy. Ideas?
