In the pursuit of knowledge, I peeled three different potatoes (red bliss, russet, and Idaho bakers), cut into french fry shapes and blanched them in water for 6 minutes, then drained them, patted them dry, and fried them. They took a long time to brown. (10 minutes/serving) I think that boiling them didn't drive off the water as prefrying does. Also, the sugars which brown on the surface may have boiled off into the water. The surface was porous, and slightly crispy, but not crunchy as a golden brown fry is. Red bliss were the best. They were meltingly tender inside, and brown on the outside, without being soggy. Russets were ok, while the Idaho potatoes were like the worst fast food fries you've had-like cold tasteless MacDonald's fries. Maybe we boiled off the flavor, too. If anyone had said to you that these three were a new type of "lite" fry, you would have agreed, but secretly suspected that there was every bit as much fat as in the regular type.
