I made half a batch, enough for three custard cups. I had to bake it for 90 minutes instead of the recommended 40 - and I still had slippery jiggle in the middle! I would jump to the conclusion that my oven is broken, but it was producing large amounts of heat, even as I stuck my head in the door peering down at my sad custard cups. As B. delicately put it, "Did you leave out any ingredients? Something you needed..." There are four ingredients! Surely as a somewhat competent kitchen clutterer, I could do justice by four little ingredients. (But I did double check the recipe just to make sure and kindly thank him for his suggestion.)
After being chilled, the little cups perked up a bit and were tasty. It was a nice little treat after work today, and a nice change to all the recent chocolate consumption. Thanks to Bridget of The Way the Cookie Crumbles for picking this one out.
