In some areas of the USA, particularly in the Ohio River Valley, this delicacy is still found on the menu. Made from sliced calves or pig brains that have been heavily battered and deep fried, this dish was brought over by immigrants from Germany and Holland who were keen on eliminating any sort of waste. Heavy on the calories, these sandwiches are typically served accompanied with mustard and pickled onions. Most of the flavour in the sandwich comes from the batter, with the brains having a mild taste and custardy texture.
