Hoooweee! I just love potatoes. And I LOVE french fries. I love them shoestring and crinkle cut. I love steak fries, fresh cut fries, skin-on fries, boardwalk fries, and even the hoity-toity frites. Ever been to Houston's? (a chain, I know!) But their fries are about as thin as you can get...more like a matchstick fry...and always perfectly done. I love them.
The way I see it, crinkle cuts hold the ketchup better (especially the ketchup out of a plastic squeeze bottle...natch
). Shoestrings are for dunking in the ketchup, not putting on top. But in all honesty, I am a purist. Just the potatoes and the salt, and I am good to go. No condiments, no vinegar.
