Unlocking Ancient Recipes: The Groundbreaking Study on Mesolithic Pottery
Recent research has transformed our understanding of prehistoric diets in Europe, revealing that hunter-gatherer-fishers crafted sophisticated meals far more varied than previously imagined. By scrutinizing charred food crusts adhering to ancient pottery shards, scientists uncovered evidence of deliberate combinations of fish and a broad array of wild plants. This discovery challenges long-held assumptions about simple, meat-heavy subsistence and highlights the culinary ingenuity of early Europeans.
Led by archaeobotanist Lara González Carretero at the University of York's BioArCh facility, the study analyzed 58 pottery fragments from 13 sites spanning northern and eastern Europe. Dating from the 6th to 3rd millennium BC—primarily the Mesolithic period (Middle Stone Age)—these vessels originated from coastal lagoons, riversides, and lakefronts in regions like the Don River basin in Russia, the Upper Volga and Dnieper-Dvina areas, and the Baltic zone across Latvia, Lithuania, Poland, Germany, and Denmark.
Traditional dietary reconstructions relied heavily on lipid residue analysis, which favors fatty animal products like fish due to their preservation in pottery pores. However, this new approach integrated scanning electron microscopy (SEM), optical microscopy, and bulk isotope analysis to spotlight plant microremains often overlooked.
Methods Revolutionizing Archaeological Food Analysis
The methodology marked a pivotal advancement in archaeobotany. Researchers first visually inspected charred crusts under microscopes to spot plant tissues, starch granules, and seeds. SEM provided ultra-high-resolution images of microstructures, distinguishing plant cell walls, phytoliths (silica plant skeletons), and even fungal hyphae from cooking processes.
Chemical tests confirmed animal components—predominantly freshwater fish lipids—while plant identifications drew from comparative botanical databases and experimental archaeology. To validate findings, the team replicated ancient cooking in modern pottery over open fires, simmering carp with foraged plants like guelder rose berries (Viburnum opulus) or Amaranthaceae seeds. These experiments replicated the crust formations, proving intentional culinary pairings.
This multi-proxy technique, funded by the European Research Council (ERC) Horizon 2020 grants, exemplifies collaborative European higher education research. Institutions like Aarhus University (Denmark) and University College Dublin (Ireland) contributed expertise in isotope geochemistry and regional archaeology.
Key Discoveries: A Plant-Dominated Feast Alongside Fish
The residues painted a vivid picture of selective foraging. In the Don River basin, pottery contained grass seeds, wild legume seeds (possibly clover), bran-like fragments, and hints of barley—suggesting porridges or stews thickened with cereals.
- Upper Volga and Dnieper-Dvina sites yielded guelder rose berries and fleshy fruits, processed to neutralize raw toxicity through boiling.
- Baltic vessels preserved Amaranthaceae family microremains (beetroot relatives like goosefoot and saltbush), alongside tubers from sea club-rush (Bolboschoenus maritimus) and flowering rush (Butomus umbellatus).
- Green leafy vegetables, bulbs, roots, and diverse seeds appeared recurrently, indicating specialized gathering.
Everywhere, fish—likely carp or perch—formed the protein base, but plants were not mere fillers; they were culinary stars, varying by locale to reflect availability and tradition.

Regional Variations Highlight Cultural Diversity
Dietary patterns weren't uniform. Don River communities favored starchy grasses and legumes, possibly for energy-dense meals during harsh winters. Volga-Dnieper groups leaned toward berries, adding tart flavors and vitamins to fish broths. Baltic fishers incorporated saline-adapted tubers and greens, suited to coastal ecosystems.
Pottery morphology correlated with use: thick-walled vessels for slow-simmered stews, thinner ones for quicker boils. This specialization underscores cultural transmission of knowledge across Mesolithic networks.
Such granularity demands interdisciplinary teams, much like today's research jobs in European archaeology departments.
Challenging Stereotypes of Hunter-Gatherer Subsistence
Popular narratives depict Mesolithic Europeans as fish-focused nomads with rudimentary meals. Yet, this evidence proves sophisticated plant processing—grinding, mixing, cooking—rivaling later Neolithic farmers. Plants supplied carbs, vitamins, and fibers, balancing high-protein fish diets and preventing deficiencies.
The selective use (favoring specific species/parts) implies deep ecological knowledge, passed orally through generations. This reframes hunter-gatherers as innovative chefs, not survivalists.
Experimental Archaeology: Bringing Recipes to Life
To test hypotheses, González Carretero's team cooked replicas: carp with Viburnum berries near flames produced bubbly crusts matching ancient SEM; ember-simmered Amaranthaceae yielded dense residues. These experiments not only validated identifications but illuminated sensory aspects—flavors, textures, cooking times.

European Universities Driving the Research
The study's success stems from pan-European collaboration. University of York's Department of Archaeology led microanalysis, Aarhus handled lipids, while Russian and Polish teams provided site contexts. Funding from ERC (grants 695539, 856488) and national bodies like Poland's National Science Centre underscores higher education's role in cultural heritage research.

Implications for Prehistoric Nutrition and Society
Beyond diet, findings illuminate social complexity. Shared recipes indicate knowledge exchange via trade/marriage, predating farming. Nutritionally, diverse plants mitigated fish-only risks like scurvy. For modern parallels, it informs sustainable foraging and wild food revival.
In higher education, it bolsters programs in bioarchaeology, training students in cutting-edge residue analysis.
Future Directions in Dietary Archaeology
Researchers plan wider sampling, DNA analysis of crusts, and proteomics for proteins. Integrating with isotopes could map seasonal menus. Challenges: crust preservation varies; climate change threatens sites.
