The gefilte fish in Joseph Wechsberg's mouthwatering description is unfortunately a dish of the past. Today, most people buy frozen or bottled brands. Good cooks, however, insist on preparing the homemade variety for Friday night and the holidays. My late mother-in-law, Peshka Gerson, made it twice a year, at Passover and Rosh Hashanah. She used her mother's recipe, handed down orally, from Zamosc, Poland. Her only concession to modernity was making individual patties rather than stuffing the filling back into the skin as described by Wechsberg. In addition, her filling was less elaborate. Years ago, when I asked Peshka for her recipe, two of her sisters-in-law were present. They all agreed that the rule of thumb is one pound of fat fish to one pound of thin. They also preferred the Polish custom of adding a little sugar. (Lithuanians say sugar is added to freshen already unfresh fish. Needless to say, Lithuanians do not add sugar to their gefilte fish.) Peshka, Chuma, and Rushka disagreed, however, on the seasonings. Chuma insisted on more salt, and Rushka explained that a little almond extract would do the trick. They both took me aside, promising to show me the real way to make gefilte fish. I have used their two suggestions as variations on Peshka's basic recipe. Make your fish Lithuanian or Polish, with sugar or without, but just remember—it's the carrots and horseradish that really count! I have been making this recipe since the mid-1970s. The only difference is that I cook the fish for twenty minutes. My mother-in-law cooked it for two hours!
