I've been making this for several years and just realized that I hadn't rated it! This is FABULOUS!!!! Better by far than the rubbery things at the grocery store, yes. Flavorful, tender, and beautiful.
My family loved it. The only thing I didn't know how long to cook it over hot water meant. So I just did a like a double boiler. I used a metal boil over a pan of boiling water. I cooked it until it was warm. It turned out great! My family loved it. I accidentally forgot the vanilla and it was still good.
My friends loved it! They asked for the recipe. It was great the unusual (stirring over boiling water kind of threw me though).
Nothing like those rubbery things at all! Very gourmet! It turned out quite like lady fingers, but better and softer. Very moist, rich in flavor. Baked in a 9x11 pan for my convenience, it cut beautifully into squares. It's excellent all on its own, very eggy and sweet, with a hint of butter from greasing the pan with butter. I'd love to find some more uses for this since it was so little work for such a wonderful treat. (the whip attachment on my Kitchenaid handheld mixer made the 10 min beating super easy)
