From Coast to Crystal: The Return of Norfolk Sea Salt
The history of Norfolk sea salt is unknown to many, yet there was a time when salt was one of Norfolk’s most valuable products.
Long before refrigeration, freezers & chilled transportation, salt was essential to daily life. Used for preserving food through the winter months, and curing fish landed along the coast, salt even drove trade between local communities. The Domesday Book of 1086 records salt production at several Norfolk settlements, meaning salt production was a thriving industry woven into the fabric of coastal life around the shores of Norfolk.
Today little evidence remains of this once essential trade, yet beneath the fields and marshes lies the remains of an industry that shaped Norfolk for centuries.
Salt from the marshes.
The story of Norfolk salt begins thousands of years ago, dating back to at least the Bronze Age. The north-west coast and tidal marshes of Norfolk, particularly between Salthouse and The Wash, provided the perfect conditions as seawater regularly flooding the landscape leaving salt-rich sediment in its wake, which the early communities learned to harvest. It was an extremely labour intensive but effective process; collecting the salt-rich silt and washing it to create concentrated brine, then boiling the brine in vessels until crystals began to form. It was a slow process, dependant on both landscape and human effort, but the value of the finished product made it worthwhile.
Preserving the catch.
Norfolk’s salt production naturally became closely tied to fishing. Famous for its vast seasonal catches of herring, coastal towns needed a method to preserve the fish, and salt became the solution. Packing the herring between layers of salt crystals or soaking the fish in strong brine drew out the moisture and slowed spoilage dramatically. This allowed the catch to be transported inland and traded beyond the county lines, as well as storing for consumption in later months. For centuries the relationship between sea, salt and fish helped sustain the coastal communities.
A disappearing industry.
Salt production was at its peak during the Middle and Late Saxon period, with large excavations found around King’s Lynn and Gaywood revealing clay-lined tanks and filtration pits. But as with many traditional industries, Norfolk’s salt production eventually faced challenges it could not overcome. Competition from producers in Cheshire lead the decline, who were able to extract salt from natural brine springs more efficiently and at a greater scale. As road networks improved, cheaper salt could be transported across the country, making life increasingly difficult for coastal production.
At the same time the landscape of Norfolk was also changing. Large areas of marshland were embanked, drained and claimed for agriculture. Land that had once produced salt now became productive farmland. By the later 13th century commercial salt production in Norfolk had all but vanished.
Bringing back Norfolk sea salt
Some stories have a way of returning.
In 2024, Norfolk residents Ben & Frances Jackson found themselves asking a simple question – why doesn’t Norfolk make sea salt anymore? Being regular visitors to local markets, pubs and restaurants they were surprised that a county with such a deep connection to the sea and local produce didn’t produce its own salt. This curiosity became an obsession, and soon after, a business.
After researching the historical methods of salt production and experimenting with different approaches, they settled on a process that felt true to both Norfolk’s heritage and landscape. The result was Saltwrights.
Filtered sea water is drawn from the North Norfolk coast, before making its journey inland to Salle Moor Hall Farm, a working organic farm in the heart of the county. Once deposited into purpose built evaporation tunnels, the sea water begins its slow transformation powered by nature rather than industrial process. The sun and wind gradually concentrate the mineral rich brine until salt crystals are formed and harvested by hand. The process takes weeks rather than hours, creating salt that reflects the season and character of Norfolk. No two harvests are the same, which the Saltwrights compare to a wine vintage – each batch captures a particular moment in time and place.
Conclusion
While separated by centuries, the landscapes that once supported Norfolk’s salt production still shape the salt produced today. The sea remains the starting point, the weather an essential partner. Saltwrights have reconnected the county with a craft rooted in its coastal past and brought a forgotten part of Norfolk’s heritage back to life.
