The Fascinating History of Icelandic Lava Bread

The history of Icelandic lava bread is intimately linked to the unique geography of this country. In a land where wood resources were scarce and electricity didn’t yet exist, Icelanders had to be ingenious to bake their daily bread.

For centuries, inhabitants observed that certain areas of the ground were naturally hot due to geothermal activity. They then had the brilliant idea of burying their bread dough in these soils to bake it slowly. This cooking method has been passed down from generation to generation, becoming an important part of Iceland’s culinary heritage.

Traditional rye bread, called “hverabrauð” (literally “hot spring bread”) or “rúgbrauð” in Icelandic, holds a special place in local cuisine. Unlike our French habits where bread is mainly consumed with savory dishes, this dense and slightly sweet bread accompanies both main meals and snacks, often served with fresh Icelandic butter or seafood products like smoked trout.

Why “Lava Bread”?

You might wonder why we call it “lava bread”? This name directly refers to the volcanic forces that heat Iceland’s soil. Iceland is located on the Mid-Atlantic Ridge, an area where the North American and Eurasian tectonic plates separate, creating intense volcanic and geothermal activity.

This unique geological position allows energy from the Earth’s center to rise to the surface, naturally heating the ground to perfect temperatures for slow bread baking. In some regions, like Laugarvatn, the ground can reach 80-100°C at shallow depths, creating a natural and ecological oven!

It’s this direct connection with volcanic energy that gave rise to the term “lava bread” – a bread that literally draws its baking from the same energy that creates Iceland’s spectacular volcanic eruptions and iconic geysers.

The Baking Experience at Laugarvatn Fontana 🍞

Laugarvatn Fontana is located on the shores of Lake Laugarvatn, about 77 km from Reykjavik, directly on the famous Golden Circle route. This complex combines geothermal baths and a center dedicated to the lava bread tradition, making it a perfect stop on your itinerary.

The site itself is beautiful, with a breathtaking view of the lake and surrounding mountains. The modern facilities blend harmoniously into this stunning natural landscape, creating an atmosphere that is both authentic and comfortable.

The geothermal bread baking workshop lasts about 30-40 minutes and takes place daily at 11:45 am and 2:30 pm throughout the year. Between June 1st and September 30th, an additional session is offered at 10:15 am to accommodate more visitors during the high tourist season.

Dough Preparation

The experience begins with a demonstration of dough preparation. The traditional recipe is surprisingly simple, mainly using:

• Rye flour (main ingredient)
• Sugar (which gives its characteristic slight sweetness)
• Milk
• A pinch of salt
• A bit of yeast

The guide explains each step with passion, often sharing personal anecdotes about how this tradition continues in Icelandic families. What struck me was the rather liquid consistency of the dough compared to our French breads – it looks more like a very thick cake batter.

The peculiarity of this Icelandic rye bread lies in its perfect balance between sweetness and rustic flavor. Unlike other European rye breads that can be very dense and acidic, the Icelandic version is slightly sweet and incredibly soft thanks to its slow cooking.

Burying the Bread

The most fascinating part of the experience is undoubtedly the moment when the guide explains how the dough is buried in the hot black sand. At Laugarvatn Fontana, they use metal pots with airtight lids to contain the dough.

The guide then takes you outside, to the geothermal area located by the lake. That’s where the magic happens! With a shovel, he digs into the black sand to reveal… another pot that was buried the day before! The ground temperature in this area reaches about 97°C, creating ideal conditions for slow cooking for 24 hours.

You can feel the heat emanating from the ground by placing your hand a few centimeters above the sand, and even see steam escaping into the cold Icelandic air. It’s an impressive demonstration of the island’s geothermal power and the ingenuity of Icelanders who have been able to exploit it sustainably.

The freshly prepared dough is then buried in the same place, ready to be retrieved the next day for another group of visitors. This daily cycle perpetuates a centuries-old tradition, using exactly the same principles as past generations.

Unearthing and Tasting

The moment everyone eagerly awaits arrives: the unearthing of bread baked for 24 hours! When the guide removes the pot from the hot sand and opens the lid, a delicious smell of freshly baked bread fills the air.

The appearance of the bread is surprising for those who have never seen it: it’s dark brown, almost black, with an incredibly moist and dense texture. The guide slices it in front of you, revealing its soft and slightly sticky crumb.

Tasting is the highlight of the experience. Each participant receives a slice of warm bread served with a generous portion of Icelandic butter that instantly melts upon contact with the bread, and a piece of local smoked trout. This combination might seem surprising, but I assure you it’s a perfect marriage of flavors!

The bread’s flavor is truly unique: slightly sweet with caramelized notes, a melt-in-your-mouth texture, and a subtle aftertaste reminiscent of the volcanic terroir in which it was baked. The smoked trout adds a salty note that perfectly balances the bread’s sweetness.

The Science Behind Geothermal Cooking

Iceland is one of the few places in the world where geothermal energy is so easily accessible. This island is located on what’s called a geological “hot spot,” where magma is particularly close to the Earth’s surface.

Rainwater seeps deep into the ground, where it’s heated by the proximity of magma before rising as hot water or steam. This phenomenon not only creates Iceland’s famous hot springs, but also heats the ground to ideal temperatures for slow cooking.

At Laugarvatn, the ground temperature naturally maintains around 97°C, which is perfect for slow and uniform cooking. This method has several advantages over conventional cooking:

• It preserves the bread’s moisture, making it incredibly soft
• It develops more complex flavors thanks to the cooking duration
• It uses a 100% renewable and non-polluting energy source

From an ecological perspective, this cooking method is remarkably sustainable. It uses no fossil fuels and produces no CO2 emissions, perfectly aligning with Iceland’s commitment to clean energy and with our values as environmentally conscious Curious Souls.s les énergies propres et avec nos valeurs d’Âmes Curieuses soucieuses de l’environnement.

How to Recreate Lava Bread at Home (Adapted Version)

Back in your home country, you might be tempted to recreate this experience to share a bit of Icelandic magic with your loved ones. Although the geothermal cooking method is impossible to reproduce exactly (unless you have a volcanic garden!), here’s an adapted recipe that comes close:

Ingredients for Icelandic Rye Bread:

• 500g rye flour
• 250g wheat flour
• 1 tablespoon dry yeast
• 2 teaspoons salt
• 100g brown sugar
• 250ml warm milk
• 250ml warm water
• 2 tablespoons maple syrup (to replace the slightly smoky taste)

Preparation:

1. Mix the flours, sugar, salt, and yeast in a large bowl
2. Gradually add the milk, water, and maple syrup, mixing until you get a fairly liquid dough (like thick cake batter)
3. Pour the preparation into a well-greased and floured loaf pan
4. Cover tightly with aluminum foil

Adapted Cooking: To simulate slow geothermal cooking, use a slow cooker or an oven at very low temperature:

• Slow cooker option: Cook on low for 8-10 hours
• Oven option: Preheat to 100°C and cook for 6-8 hours

The bread won’t be exactly like the one tasted in Iceland, but this slow method will produce a soft texture and developed flavor that comes close.

Serve it like the Icelanders: warm with quality salted butter and, if possible, smoked salmon or trout!
