For my Ashkenazi ancestors, the towers of meat you can find at the Jewish deli were nonexistent. Instead, their kitchens would be full of fresh, regional and seasonal vegetables, an assortment of pickles and, if they were lucky, some dairy. Meat and fish were expensive rarities until the industrialisation of meat production in the early 20th Century. That's why the gefilte fish I'm making now is a vegetarian imitation adapted from a century-old recipe using a purée of salsify (oyster plant), cashews and onion mixed with eggs and matzo meal, shaped into disc-like quenelles for poaching, then topped with one sliced carrot and sinus-clearing horseradish.
