In my brief research on the Lincoln Del yesterday, I didn’t come across a recipe for the restaurant’s matzo ball soup, but I did find one for the chocolate pie, which if I remember correctly was a specialty.
I’m a bit leery of the raw eggs — I would look for pasteurized ones to use in this recipe.
Lincoln Del Chocolate Pie
Cream ¼ pound butter and ¾ cup powdered sugar. Melt ¼ pound chocolate chips and add to creamed mixture. Add ½ teaspoon vanilla. Beat in 3 eggs, one at a time, into the chocolate mixture, until thoroughly combined.
Pour chocolate mixture into a baked pie shell and chill. Top with whipped cream and chocolate curls.
