Ancient Bread Recipe Recreated From Old Yeast

Ancient Turkish Bread Recipe Revived After 5,000 Years, Captivating a Modern Audience

A remarkable partnership between archaeologists and bakers in Turkey's central region has resurrected a culinary formula from 5,300 years ago. The project began after an extraordinary discovery at a settlement from the Bronze Age, offering a tangible connection to the daily lives of ancient Anatolian people. This initiative not only provides a taste of the past but also carries important lessons for contemporary challenges like climate change and food sustainability. The successful recreation has sparked immense public interest, with the old-style baked goods flying off the shelves and capturing imaginations worldwide.

A Burnt Offering to History

A group of specialists, while excavating at the historic site of Kulluoba Hoyuk near modern Eskisehir, made a stunning discovery in September 2024. They uncovered a small, round, and heavily scorched baked good buried beneath a house’s threshold, dating to around 3300 BCE. This location, under continuous excavation since 1996, is among the first urbanized communities on the Anatolian plains. It was a region where settled farming societies began flourishing between 3300 and 3000 BCE. The find is exceptional, as organic materials like baked goods rarely survive for millennia.

The Bronze Age Kitchen

The Kulluoba settlement was a medium-sized urban centre with evidence of commerce, crafts, farming, and mining. Inhabitants from this era, likely the Hattians who preceded the Hittites, had established a degree of social order. Finding a whole baked item, rather than just crumbs, offers a rare glimpse into their diet and culinary practices. The bread’s placement suggests it was not discarded but intentionally interred. A portion had been torn from the item before it was burned and buried, leading archaeologists to believe it was part of a ritual to ensure prosperity for the new home.

An Archaeologist’s Rare Find

Murat Türkteki, the excavation director from Bilecik Şeyh Edebali University, emphasised the discovery's importance. He explained that finding bread so well-preserved is incredibly unusual in his field. Typically, only fragments or crumbs survive the passage of time. The key to this item's preservation was its carbonisation. This burning process, followed by its careful burial, protected the foodstuff from decomposition. This allowed its structure to remain largely intact for more than five millennia. It stands as the oldest known example of a fermented and baked food product discovered in this state.

From Dig Site to Display

Following its excavation, the historic baked good embarked on a new journey. It became a prized exhibit inside the Eskişehir Archaeological Museum, situated in the city's heart. Since its unveiling, the millennia-old bread has drawn considerable attention from both the public and local officials. The display allows visitors to see a direct link to their ancestors' lives. It is a tangible piece of history that tells a story of food, ritual, and daily existence in the Bronze Age. The artefact serves as a powerful reminder of the region's deep cultural heritage.

A Mayor's Vision

The discovery deeply moved Ayse Ünlüce, Eskisehir's mayor. She expressed how the find offered a profound connection to the people who inhabited the area many millennia prior. Inspired by the artefact, she initiated a conversation with Murat Türkteki about potentially replicating the old bread to honor the city's history. This idea quickly evolved into an ambitious project. The aim was not just to reproduce a formula but to resurrect an element of cultural history and share it with a modern audience, bridging the gap between past and present.

Unlocking an Ancient Recipe

To uncover the secrets of the Bronze Age baked good, archaeologists subjected it to detailed scientific analysis. Microscopic examination in a laboratory revealed its core components. The analysis indicated the circular, flat item's composition included coarsely ground emmer wheat, a primitive grain known locally as 'gernik'. It also contained lentil seeds and an unknown plant's leaf. Researchers believe this leaf functioned as a natural leaven, causing the dough to expand. The study concluded the dough underwent fermentation before being baked at a high temperature.

The Ghost Grain of Anatolia

The primary ingredient, emmer wheat (Triticum dicoccum), was among the initial domesticated cereals, cultivated widely across ancient Mesopotamia and Egypt. While it was a staple in the Bronze Age, this specific ancestral variety is no longer found in modern Turkey. Emmer is known for its tough husk, which protects the grain but requires more effort to process. It is also recognised for being rich in protein and low in gluten, making it a nutritious option. The disappearance of this primitive grain from the local agricultural landscape posed a significant hurdle for the recreation project.

A Modern Stand-In

Faced with the challenge of sourcing an extinct grain, the project group searched for the closest possible substitute. They selected Kavilca wheat, a heritage variety with a genetic profile that resembles the old emmer. Kavilca is another primitive variety of hulled wheat, historically grown in the high, arid regions of northeastern Turkey, particularly around the Kars province. Known for its resilience to cold and drought, Kavilca shares emmer's nutritional benefits. Its use allowed the bakers to mirror the initial formula's characteristics as closely as they could.

The Science of Leavening

The analysis of the historic bread revealed fascinating details about Bronze Age baking techniques. Researchers discovered white residues on the back of the item, identified as phytoliths, which are microscopic plant remains. These traces, likely from leaves, suggest they were part of the fermentation process, acting as a form of wild yeast. This method of leavening indicates a sophisticated understanding of food processing. The item was fermented and then baked at a temperature exceeding 150 degrees Celsius, resulting in a well-cooked crust and a softer centre, showcasing the bakers' skill.

Bakers Turn Back Time

The scientific findings were handed to a group of professional food artisans from the Halk Ekmek establishment in Eskisehir. The name Halk Ekmek translates to "People's Bread," a fitting partner for the project as it is a municipal bakery established to provide affordable and nutritious options to the community. The artisans took on the challenge of reproducing the 5,300-year-old baked good. They combined the knowledge from the lab with their own skills. This collaboration between science and craft was crucial to reviving the old culinary formula for the public to experience.

The Baking Process

The group at Halk Ekmek meticulously worked to reproduce the historic item. They combined Kavilca wheat flour with lentil flour, cooked lentils, and bulgur to mirror the original composition identified by the archaeologists. The dough was hand-shaped into flat, round items, each about 12 centimetres wide, matching the dimensions of the old original. Following the ancient method, the dough portions were fermented and then baked. The resulting product is a dense, filling, and preservative-free food with a low gluten content, staying true to the Bronze Age formula.

A Taste of the Bronze Age

The modern recreation, named "Küllüoba bread," was an immediate sensation. The bakery produced an initial quantity of about three hundred items daily, and the entire stock vanished within a few hours of becoming available. Customers queued up, keen to experience a flavor from the past. One customer, Suzan Kuru, told reporters she rushed to the bakery, afraid the items would be gone. She was driven by curiosity about the flavour of such an old food. This enthusiastic reception demonstrated a powerful public appetite for products with deep cultural resonance and a compelling story.

More Than Just a Baked Good

This project has significance far beyond its culinary appeal. The revival of the Küllüoba bread has sparked important conversations about agricultural sustainability, especially in the face of modern climate challenges. Mayor Ayse Ünlüce highlighted this, noting that Eskisehir province, once rich in water, now suffers from drought. The project serves as a lesson from their ancestors. It promotes the cultivation of less water-intensive crops like Kavilca wheat. It demonstrates how ancient wisdom can offer practical solutions for contemporary environmental problems and enhance food security.

Kulluoba’s Other Secrets

The bread is just one of many fascinating discoveries at the Kulluoba Hoyuk site. Excavations have revealed a settlement with a unique history, including evidence of strange burial rituals for its buildings. Archaeologists have found entire houses, complete with hearths and silos, that were deliberately cleaned, emptied, and then carefully filled with sterile red soil before the inhabitants moved on. In some cases, animal sacrifices were placed in doorways, and pottery was ritually smashed, hinting at complex spiritual beliefs. These findings provide a broader context for the bread’s ritualistic burial.

The Legacy of Anatolian Grains

Anatolia is a crucial centre for the history of wheat. Göbekli Tepe, another site in the region, holds clues to the transition from hunter-gatherer societies to settled farming life over 11,000 years ago. Of the 22 known wild wheat species, 14 still grow in Anatolia today, making it a vital hub of genetic diversity. The story of the Küllüoba bread is part of this long history. It demonstrates how primitive grains like emmer and Kavilca have been central to life in the region for millennia, shaping its culture, diet, and agricultural traditions.

Food as a Historical Document

Food artifacts like the Kulluoba item serve as invaluable historical documents. They provide direct evidence of what people ate, how they prepared their food, and the ingredients they cultivated. Such discoveries connect us to the past in a uniquely personal and sensory way. While ancient tablets from civilizations like the Hittites list bread types and their ingredients, they rarely provide full recipes. Recreating foods based on archaeological analysis allows for a deeper, more practical understanding of these old culinary traditions, turning abstract knowledge into a tangible experience.

Challenges in Culinary Archaeology

Accurately recreating ancient foods is a complex endeavour fraught with challenges. The absence of original ingredients, like the extinct emmer wheat in this case, necessitates finding suitable modern substitutes. Identifying every component can also be difficult; the specific plant leaf used for leavening the Küllüoba bread remains unknown. Furthermore, old preparation methods, from milling grain with basalt stones to baking in clay ovens, must be inferred and replicated. Despite these obstacles, each attempt provides new insights into the resourcefulness and skill of ancient peoples.

The Historic Loaf's Future

The incredible success of the Küllüoba bread project has opened the door for future initiatives. Mayor Ayse Ünlüce has expressed a strong desire to revive the cultivation of Kavilca wheat in the Eskisehir region. She is promoting it as a drought-resistant and valuable crop. This could support local farmers and contribute to a more sustainable agricultural system. The project also serves as a model for how other communities can explore their own culinary heritage. By combining archaeological research with local craftsmanship, it is possible to rediscover and share ancient traditions in ways that are both educational and economically beneficial.

The tale of this 5,300-year-old baked good is a testament to the enduring power of food to connect us across time. From a ritual offering in a Bronze Age house to a sold-out item in a modern Turkish bakery, this historic baked item has completed an incredible journey. It not only fills a gap in our understanding of the past but also offers nourishment for the future, reminding us of the timeless wisdom held within the grains of our ancestors.
