Crisp Hungarian pickled round apple peppers (almapaprika) preserved in a tangy vinegar brine with mustard seeds, coriander, and allspice.
Wash the peppers, trim the stems slightly, and prick each pepper twice with a wooden toothpick to allow brine penetration.
Combine water, vinegar, sugar, salt, mustard seeds, coriander, allspice berries, and bay leaf in a saucepan and bring to a rolling boil.
Pack the peppers tightly into clean sterilized glass preserving jars.
Pour the boiling brine and spices over the peppers to submerge completely, seal tightly, and cool. Serve as a zesty starter or accompaniment.
