Early in the pandemic my partner and I decided that, since we couldn't actually travel anywhere interesting any more, we'd instead do our weekly shop at a different international supermarket every week.
We live in the San Francisco Bay Area so there are a LOT of international supermarkets!
We found Indian, Mexican, South American, Chinese, Japanese, Russian, Middle Eastern - but my favourite ended up being the Korean Kukje supermarket in Daly City.
Eventually we realized that the trick is to go with at least one recipe in mind, which turns it into a more structured effort to find those ingredients (and then impulse buy lots of other interesting things).
