Mistakes were made in the construction of this tart. It was supposed to turn into a lemon-polenta cake so beautiful on Nigel Slater's Web site that I couldn't resist. Things came a little undone in my kitchen, unraveling slowly and then nearly landsliding into defeat.
At some point Friday, I came up with a decent idea. The goo tasted good, and I hated the thought of just throwing it away, plus there was so much of it, it seemed like it might make a good topping to a pie.
