How this recipe got into my files I no longer recall. It had been there for years, and, when I finally got around to trying it, I wished I had done it sooner. I ought to have known that amaretti and chocolate make an ideal match, neither one too sweet, both with that fine, faint touch of bitterness so bracing on the palate. This is not a cake that rises much, but it is moister than its low profile might lead one to suspect. There are few desserts that a topping of homemade whipped cream does not do some good to, and on this one, I think, it would be particularly apt.
