The story the reviews tell

Hapanvelli is a South-Eastern Finnish gruel that straddles the line between soup and something deeper—built on rye sourdough starter, potatoes, and peas, it develops a distinctive sour note over the course of an hour's cooking. Served with a knob of butter melting into cold milk, it's the kind of humble, fermented dish that anchors a region's identity so completely that Virolahti built a festival around it.

What makes this version distinct

Hapanvelli (Finnish pronunciation: [ˈhɑpɑnˌʋelːi], lit. 'sour gruel') is a traditional South-Eastern Finnish dish that resembles pea soup but has a more sour flavour. It takes roughly an hour to prepare hapanvelli, which is made from a rye sourdough starter, potatoes and peas. It is traditionally served with a pat of butter and cold milk. Hapanvelli is a traditional dish of the Virolahti municipality which has an annual summertime Virolahti Week (Virolahti-viikko) during which hapanvelli is sold. There is also a contest during Virolahti Week in which the best cook gets the title of Miss Hapanvelli (Hapanvellimissi).
