I was wondering the same and got curious enough for a quick search. Saw someone recommending Branston Pickle and it looks similar
Branston Pickle is made from a variety of diced vegetables, including swede, carrots, onions and cauliflower pickled in a sauce made from vinegar, tomato, apple and spices.[9] While not a chutney, Branston Pickle is sweet and spicy with a “chutney-like” consistency, containing chunks of vegetables in a thick brown sticky sauce.[9]
