Germany has sauerkraut, Thailand has naem (fermented pork sausage), Sweden has surströmming (fermented herring) — it seems every culture has its own traditional fermented food.

Here are five classic yet freshly popular fermented foods to add to your ingredient repertoire, if you haven't already. They're all mostly a little more accessible than, say, Iceland's hákarl (rotten shark).
