Rollmops
Rollmops are the pickled herring rolls of the North Sea and Baltic coasts, pinned with a wooden pick around gherkin and onion and kept in a jar of spiced vinegar; in Berlin and Hamburg they are the classic morning-after breakfast and a fixture of New Year's Day tables. Making them at home takes a week of fridge time but very little work. Because the fish is never cooked, use herring that has been frozen at −20 °C for at least 24 hours (most fresh 'sashimi-grade' or commercially frozen fillets qualify; ask your fishmonger), and keep everything chilled. Rollmops are not for pregnant women, young children or anyone with a weakened immune system. Chef's tip: let the jars rest a full five days; the vinegar needs that long to firm the flesh and soften the tiny bones.
