Announcer: Here's Alton Brown for Couch Potato Weekend
Most folks know that high-starch spuds like this, fall apart when cooked while low-starch models keep their shape even after boiling. But what if you were to come across a spud you'd never seen? [holds an odd looking potato up] How would you know how to cook it? Well, luckily starch is denser than a brine composed of one part salt and eleven parts water. So, if the suspect spud sinks, baking is an option. If it floats, it's a witch ... or maybe just a low-starch model waiting to star in your next potato salad.
Alton Brown here for Couth Potato. True spud-lovers know that bakers [potatoes] do best when roasted right on the rack. Of course, if you've got a dozen diners, you may need to consider vertical integration via a muffin tin. Just avoid poking steam vents in the ends of the potatoes sitting down inside the cup. Otherwise, you'll end up with soggy bottoms. Definitely not good eats.
[AB is ironing and tries to spray starch on the pants, the can is empty]
No trouble. I was going to make mash potatoes tonight anyway.
[peels some potatoes, slices them, soaks them in water]
[shakes bottle and sprays onto pants, continues to iron]
The year, 1853. The place, Saratoga Springs, New York. Railroad magnate, Cornelius Vanderbilt is served a plate of fried potatoes which he thinks are just too darned thick. So, he sends them back to chef George Crum who, insulted by the big wig's insolence, decides to slice the next batch so wafer thin that when fried, they don't even look like potatoes anymore. Intrigued, Vanderbilt gives them a try. [tastes] And thus is born, the Saratoga or potato chip.

HW: [stirring watery soup] Oh, no. Watery soup again.
[Ten Minutes Later]
HW: Yum. What do you call this masked marvel.
HW: Dinner's saved.
GUEST: Paul Merchant
Why is it, if you whip potatoes in a food processor you end up with something like paste? Well, a potato's like a gas tank full of little fuel cells called starch. When heated, these absorb the water around them swelling to several 100 times their original size. Now at this point they can be converted into a light, fluffy mass. But if you overwork them, the starches will rupture [pops huge balloon Paul is holding] leaving you with a big mess.
GUEST: Mr. Sweet Potato
AB: Hmm. Mr. Sweet Potato, I believe you are suffering from an identity crisis. You see, as a member of the Morning Glory family, you can't be a potato. And despite what all those can labels say, you're not a yam either, because yams are lighter, sweeter and from Africa, not South America. I'm afraid you're going to have to settle for being delicious and nutritious. Now, tell me: what comes to your mind when I say the word, 'marshmallow'?
Hi. Alton Brown here. Ever wonder why fast food fries are
skinny? They have to be because they're frozen right after they're cut. You see,
when a spud drops below 40 degrees, its starch converts to sugar very quickly.
