Communist Bulgaria was home to a furtive cooking craze on a massive scale: women swapping recipes on scraps of paper, with strangers on trams, even at funerals. The historian and writer Albena Shkodrova sees this fascinating phenomenon as a form of subversion; we called her up to ask why. Also this week: Happy Birthday Schengen, an accidental invasion, and an end to Sweden's longest-running murder mystery.

Protests over the death of George Floyd have been spreading on this side of the Atlantic, from Britain to Hungary. This week we're talking about what makes the European anti-racism protests different, with the artist and cultural critic Quinsy Gario. We're also talking about Prague's mysterious poisoned suitcase, and a possible post-COVID rail revolution.

Less than a fifth of the biographies on Wikipedia are those of women; Rebecca O'Neill is part of a movement to fix that. We talk to her about her quest to write famous Irish women into the Wikiverse, as well as how the site helps minority languages to stay alive. Also this week: Merkel rises above it, and theatre gets political in Albania.

Last year a terrible disaster struck the Losharik, a highly advanced Russian submarine. But what happened? And what was the submarine doing so close to European shores? This mystery has fascinated the Norwegian journalist Thomas Nilsen, one of the authors of a New York Times investigation into the Losharik disaster. We talked to him about why Russia is so interested in what lies beneath these waters. Spoiler alert: your internet connection depends on it.

This week we've got a cultural bonanza for you. We're talking about Poland's Netflix tax and the new drive-in cinema in Vilnius, as well as all the TV and online concerts we've been bingeing on. Plus, a great interview with the French screenwriter Noé Debré about Parlement, the European satire we've been waiting for.

This week we bring you: coal, chess, and the circular economy. We speak to Esther Goodwin-Brown of Circle Economy about the economic model that's getting environmentalists all hot and bothered. We're also talking about why Europe's fallen out of love with the black stuff and why chess is getting a revamp. Plus, metal detectors — because what would this podcast be without metal detectors?

The superstar illustrator Christoph Niemann is on a mission to better understand Europe. 'In Praise of a Normal, Boring Country', the latest installment of his New York Times visual essay series, took him to Estonia. We rang him up in Berlin to talk about his trip and a bunch of other stuff. Also this week: Dominic gets to grips with debt mutualisation, and Katy gets to grips with mittens.

There's a bunch of interesting stuff happening in Poland right now, so we rang up our favourite Polish journalist Ania Jakubek to untangle it for us. Also this week: blue tits, volcanoes, mutant enzymes and an Easter panda.

The Irish writer Mark O'Connell spent three years meeting people who are preparing for the end of the world. At a time when a lot of us have been gripped by a general sense of doom, we had a weirdly reassuring chat about the apocalypse. Also this week: big developments in Central Europe, bouncy pavements, and a celebration of the theremin.

In this time of crisis, many, many people are watching marbles roll down miniature race tracks. We talk to Dion Bakker, one of the Dutch brothers behind the hit marble-racing YouTube channel that's filling the void left by cancelled sports events. We also catch up with atmospheric physicist Meganne Christian, who spent a year in Antarctica, to hear her tips on surviving isolation. Also this week: Viktor Orbán's terrifying power grab, and trees, lots of trees.

Calming things are much needed this week, so we're talking about lakes and we're talking about dogs. Our guest is the poet and author Kapka Kassabova, whose latest book To The Lake is a beautiful account of life on the borders of Greece, Albania and North Macedonia. We're also celebrating cleaner skies, human-canine relationships, and putting booze to good use.

The show goes on. This week, aside from bringing you some positivity from around the continent, we're talking to someone who turned something terrible into something empowering. Emma Holten was 20 years old when nude photos of her were leaked onto the internet without her consent. We gave her a call in Copenhagen to hear about her inspiring fightback. Also this week: good dogs and good decisions in Spain and Greece.

This week, the distances travelled in search of love and safety. The Finnish novelist and playwright Saara Turunen has written beautifully about what it's like to navigate a relationship between Helsinki and Barcelona. We chat to her about European culture clashes and what feminism looks like in the two countries she lives between. Plus, Europe's failed refugee policy, magical taps, and ill-chosen words by a billionaire populist (no, not that one).
