Lüneburg's salt was needed in order to pickle the herring caught in the Baltic Sea and the waters around Norway so that it could be preserved for food inland during periods of fasting when fish (not meat) was permitted.
Lüneburgi soola vajati, et marineerida Läänemerest ja Norra vetest püütud heeringat, nii et seda sai paastuajaks sisemaal toiduks säilitada, kui kala (mitte liha) oli lubatud.
