After the dough had been refrigerated the requisite time, I weighed the entire piece of dough, divided that by 6 and found that each piece of dough should weigh 2 3/8 ounces. I then rolled the dough using very little flour and a pasty cloth and rolling pin cover. This is also a Father Paul technique and one I've adhered to for almost 50 years.
I found that you had to treat the dough with care. I moved it from the pastry cloth to the tartlet pans (I did not remove the bottoms) with a bench scraper. After baking the crusts, the rest of the recipe was easy. I had previously made chocolate chip biscotti and that was a learning experience. After making three batches (all jaw breakers), I learned from my daughter that a small amount of fat in a biscotti recipe will make it far less hard. I used an ice cream scoop to fill the tartlets, but found it took about two scoops, not one, to fill each pan. I baked the tartlets for the full time.
Now, the appearance and taste. I thought the tarts were attractive, more elegant certainly than a wedge of pie, and would be nice served for company. But, were they perhaps too big for one person to eat after a meal? My husband and I split one, and that was plenty. And, the taste wasn't quite as over-the-top as I expected. In a nutshell: I prefer my favorite chocolate pie recipe -- Aunt Catfish's Boat Sinker pie. Here is a link to that recipe: http://community.tasteofhome.com/community_forums/f/33/t/744838.aspx
What to do with all those left-over egg whites? I am freezing some to use as "glue" to adhere seeds to whole grain breads. I am also going to make meringue cookies with four of them. There are lots of recipes for meringue cookies on the internet. I think I'll try peanut butter. And, then, of course, there is always angel food cake.
