Yes, I remember that one, too,
and Cooks Illustrated said that it was (my paraphrase,) a good idea that did not live up to its promise.
A plug, in general, for Cooks Illustrated. They are ad-free, like CR. They are NOT affiliated with Consumers Union/Consumer Reports, but Cooks Illustrated/Boston Common Press seems to have taken over the niche of food and equipment testing that CR used to do. I have several concerns. When CR used to do food projects, they made an effort to test brands that were not just from their immediate area. Cooks Illustrated does not seem to make such an effort.
My other concern is the equipment testing. Cooks Illustrated seems to like more expensive equipment. Their 2006 test of stand mixers gave high marks to a 1000 +/- Hobart machine, and so on.
This being said, I do like Cooks Illustrated a great deal.
Whenever I have to make something requiring constant stirring, I either make it in the microwave in a big Pyrex measure, or I slip some music in my cd player, and stand facing the stove.
I like to make sauces, puddings, and the like in the microwave... they almost always need less stirring.
