Pickled young herring
They are immature female herring. Matjes is Dutch for v-vvv-vv-virgin herring. Young females that have not yet laid eggs. Traditionally they are brined with the guts still in and the pancreas does something that makes them more better but I’m not ready to start experimenting with the benefits of pancreatic spoilage. They were salted then packed in a vinegar based solution with sugar, allspice, carrots and onions. Accompanied by la ratte potatoes made better with some soured cream, lemon zest and parsley; you know, for freshness. And a nice medley of handsomely colored pickled onions.
