PHILADELPHIA - Last year, Fishtown Pickle Project took the age-old Feast of the Seven Fishes holiday tradition and created something of their own — the Feast of the Seven Pickles — a holiday cocktail party is featuring seven pickle-centric dishes paired with wines. It was such a hit that not only did they add two seatings and accept walk-ins, but they ended up with a nearly 200-person waiting list. They had so much demand that they also jarred seven types of pickles for an in-home version entitled “Pickle Party Mix.”
