As part of her recipe for Goodfellow's famous lemon pie, Leslie wrote: "A genuine baked lemon pudding (such as was introduced by the justly celebrated Mrs. Goodfellow), and is well known at Philadelphia dinner parties, must have no flour or bread whatever. The mixture only of butter, sugar, and eggs, (with the proper flavoring) and when baked it cuts down smooth and shining, like a nice custard. Made this way, they are among the most delicious of puddings…" The recipe used whole eggs in the filling, so it's improbable that Goodfellow created the lemon meringue pie - with egg yolk filling and the leftover egg whites whipped for meringue topping.
