See this herring: it made the wealth of my Provinces more surely than the gold of the Indies. Salted at sea in its barrel, it keeps for months, and no household so poor is without it. I take it straight on rye bread, with a little raw onion that whets the appetite; it costs me three cents and feeds the whole man. Wisdom, you see, lies not in the abundance of dishes, but in the right match of need and thing.

How it was made : 'Haringkaken' — the art of gutting and salting herring at sea, attributed to the legendary Willem Beukelszoon — allowed the Dutch to preserve mountains of fish in barrels. New herring ('Hollandse nieuwe') was celebrated each summer, but salted, it was eaten all year with onion and bread. It was the protein of both poor and rich.
