Hungarian Chocolate-Walnut Torte

This is a taste of prewar Hungary, from the family repertoire of my dear friend Judy Abrams, gifted teacher and poet. Based on ground walnuts and leavened only with eggs, the light, fudge-luscious cake has not a jot of butter or flour, making it Passover-perfect for meat and dairy meals.

To conclude a meat meal, serve it plain or dusted fancifully with confectioners’ sugar (a Passover recipe without cornstarch follows) or glazed with a simple chocolate icing.
