Since "Splendid Table, Recipes from Emilia - Romagna, the Heartland of Northern Italian Food" by Lynne Rossetto Kasper is the Cookbook of the Month for October 2011, I thought I'd look at her chapter entitled, "Pastas."
On p. 85 she says, "Some machines' thinnest settings still yield pasta that is too thick (Atlas brand is one).
I've given my KitchenAid mixer away. I held onto it for sometime just to roll pasta, but the roller failed. I have had the Atlas crank kind for at least 30 years.
I used it to roll out some crackers some months ago, and evidently I rolled it out too thin for crackers. They were awful. I guess I'll just have to wait to see it won't roll out thin enough for lasagna sheets or ravioli. I just can't imagine why it wouldn't, if it is too thin for crackers.
