Brandenburg's iconic Spreewald pickled cucumbers: crisp pickling cucumbers steeped in an aromatic brine of dill crowns, mustard seeds, horseradish, and vinegar.
Scrub cucumbers in cold water, trim stem ends, and soak in ice water for 2 hours to ensure crispness.
Pack cucumbers tightly into sterilized glass jars, alternating with onion rings, fresh dill crowns, sliced horseradish, and mustard seeds.
Bring water, vinegar, sugar, salt, and bay leaves to a rolling boil until sugar and salt are fully dissolved.
Pour boiling brine over cucumbers to cover completely, seal jars tightly, and let mature in a cool dark place for at least 3-4 days before serving chilled and crunchy.
