This torte is both dairy- and gluten-free. Toasted pecans lend a nutty flavor. Serve this simple dessert with lemon curd and berries for a sweet finish to your Passover meal.
Preheat oven to 350 degrees. Put egg yolks, granulated sugar, zest, vanilla, and salt in the bowl of an electric mixer fitted with the whisk attachment. Beat on medium-high speed until pale and thickened, about 4 minutes. Fold in pecans.
Beat whites in a clean mixing bowl until stiff peaks form; fold into yolk mixture. Pour into a 10-inch springform pan.
Bake until golden brown, about 1 hour (if top browns too quickly, tent with foil). Let cool on a wire rack 30 minutes. Remove sides of pan. Let cool completely. Dust with confectioners' sugar. Serve with curd and berries; garnish with zest.
