From this month's Cook's Illustrated Magazine (January 2009). Drying the bread first in the oven produces a French Toast that is crisp on the outside and soft (but not soggy) on the inside. If you purchase an unsliced loaf, cut the bread into 1/2-inch-thick slices. The French toast can be cooked all at once on an electric griddle, but may take an extra 2 to 3 minutes per side. Set the griddle temperature to 350 degrees and use the entire amount of butter for cooking.
