There’s a rye bread that’s been baked underground in geothermal springs in Iceland for generations. It’s dark, dense, deliciously sweet and it’s called Hverabrauð or Thunder Bread. I went on a whirlwind, 24 hour visit, to Iceland to discover how Thunder Bread is made and to catch a behind-the-scenes glimpse of the Celebrity Cruises and Waitrose ‘Taste of Travel’ food and travel series which is filmed with Rosie’s Deli Cafe owner and presenter Rosie Lovell.
On the Road in Iceland
We set out from Reykjavik at early doors, driving through some stunning Icelandic scenery on our journey. We had a very quick stop at Þingvellir (pronounced Thingvellir) National Park, home to the world’s oldest parliament, where we were able to check out the amazing views. We walked through one of the fault lines where the earth’s tectonic plates of the Mid-Atlantic Ridge have shifted. It was good to see the Icelandic scenery in the summer – last time I stood and looked at this view it was early February with a very wintery looking scene and a vicious wind.
We arrived at Laugarvatn Fontana and met Sigurdur Hilmarsson (Siggi), manager and chef. Siggi would be teaching Rosie how to make Icelandic Thunder Bread from a recipe handed down by his grandmother. Laugarvatn Fontana is a geothermal spa with pools, saunas and a restaurant with a strong Icelandic design vibe. It sits on the edge of Lake Laugarvatn which laps onto a black volcanic shoreline and has three geothermal springs. The springs provide energy for the entire village and the spring at Fontana would be used for cooking our Thunder Bread.
What is Thunder Bread
Thunder Bread is just a nickname, it’s actually called Hverabrauð (hot-spring bread), or rugbrauð and is a type of rye bread. It’s steam-cooked underground in a geothermal spring. Every Icelandic family’s recipe for Thunder Bread is slightly different with ‘more of this’ and ‘less of that’ and, of course, each family thinks theirs is the best. Thunder Bread is a year-round essential food in Iceland eaten with smoked trout, salmon, herring or just plain butter. As Siggi says ‘It’s pure Iceland’.
Recipe for Thunder Bread
4 cups of rye
2 cups of flour
2 cups of sugar
1 litre of milk
1 tsp of salt
Mix everything together in a bowl. Grease a metal pot so the bread won’t stick when it’s cooked. Wrap the pot tightly in clingfilm so it’s completely waterproof. Dig a hole in your thermal spring and bury for 24 hours to gently steam. I don’t know about you, but I don’t have a thermal spring in my back garden so Siggi advised to divide the mixture into four smaller tins and cook either in a bain-marie in the oven at a low temperature or in a slow-cooker.
Burying the Thunder Bread
We went outside to the lakeside to watch Siggi bury the bread in the geothermal spring. We could see steaming bubbles exploding in the black volcanic sand by the water’s edge and smell the faint, eggy smell of sulphur in the air. First, Siggi dug up the previous day’s thunder bread and cooled off the hot pot in the lake. He then buried the freshly made pots of thunder dough in the geothermal spring.
The thunder bread is taken out of its pot and neatly sliced ready to eat…
What does Thunder Bread Taste Like?
The Thunder Bread was delicious! It was very dense and almost cake-like – I ate it, still warm, without any topping – it was moist and had a faint caramel-like taste. Really yummy. If I had a thermal spring in our garden at home I’d be baking it regularly!
Why is Hverabrauð called Thunder Bread?
Apparently if you eat too much Hverabrauð you’ll experience a ‘gas situation’! Since we were getting on a flight that afternoon I only had two slices so can’t confirm whether this is farty fact or farty fiction.
Filming with Rosie
It was fascinating to be part of a film shoot and see the painstaking procedure that goes into making just a short 2-3 minute film. The crew, Rosie and Siggi patiently filmed over and over until the producer was happy with the footage and sound. I can’t even imagine the amount of work that goes into editing everything to produce the final film. The crew have worked on a number of ‘A Taste of Travel’ videos with the Celebrity Cruises and Waitrose partnership. ‘How to make ‘Manti’ in Istanbul and what goes into producing the best gelato in Florence.
We had a chance to have a quick chat with Rosie Lovell, cookery writer, cafe/deli owner and presenter before filming started. After leaving university, Rosie went to Glastonbury, came home and straight away opened Rosie’s Deli Café in Brixton – she’s never looked back. She recently opened a second Deli Cafe in Peckham – ‘I’ll only in open in places I love, she says – I’m too emotional!’ She’s very hands-on and splits her time between the two cafes cooking up breakfasts, brunches, sandwiches and cakes.
Rosie’s written two cookery books which, she says, charter her age. Her first book, Spooning with Rosie, has simple, student, comfort food. The second, Supper with Rosie, is a bit more grown up. When asked about her food/travel wishlist there was barely a hesitation. ‘Tokyo because it’s so immersive and different; overwhelming, exciting and fundamentally foreign.’ So where does Rosie head when she’s going out for a meal? Now that we have a son it’s more neighbourhood – easy, seasonal, accessible and appealing. All I want is ‘a really flipping nice supper!’ I couldn’t agree more.

Many thanks to Celebrity Cruises for inviting me along to this big Icelandic bake off!
