The crowning salad of Polish holidays and family celebrations: cooked root vegetables, sweet peas, pickled cucumbers, tart apples, and hard-boiled eggs diced into neat cubes and folded in creamy mayonnaise and mustard.
Ensure all boiled root vegetables (potatoes, carrots, parsley root, celery root) are thoroughly cooled. Cut all vegetables, eggs, pickles, and apple into uniform, neat 5mm cubes (the hallmark of an expertly made jarzynowa).
Place all diced ingredients into a large mixing bowl along with the well-drained green peas. If the pickles are juicy, squeeze excess brine out before adding to keep the salad creamy.
Fold in the mayonnaise and sharp Polish mustard. Season generously with sea salt and plenty of freshly cracked black pepper, gently stirring with a spatula so the vegetables stay distinct.
Cover the bowl and chill in the refrigerator for at least 2 hours (or overnight) so the flavours meld into a harmonious, creamy celebration salad.
