INFO: Potatoes 101


Potatoes were a staple of Peruvian civilization as early as 3500 BCE. The discovery of the Americas by Europe introduced potatoes into Old World cuisine. Recipes for mashed potatoes (Mache-Potetesse), potatoes a l'anglaise, and potatoes dites appear in Antonin Careme's Art of French Cooking in the 19th Century (1835) as dishes to be eaten during Lent.

In 2000, Amos Latteier, the "Best Fake Professor in Portland" built a battery out of 500 lbs. of potatoes. It was able to power a small sound system, which he then drove around town for people to listen to. A potato can work as a battery because the phosphoric acid in them enables a chemical reaction allowing electrons to flow from copper to zinc. One potato will generate approximately .5 volts and .2 millamperes. Once the potato is used as a battery, it is no longer edible.

Experimental psychologists Massimiliano Zampini and Charles Spence investigate whether modifying the sound made by a crunching potato chip would affect the eater's perception of the chip's staleness. The study was conducted on Pringles, because Pringles are made from reconstituted "potato goo" and are therefore uniform in size, shape and texture.

The volunteers wore headphones and sat in front of a microphone with footpedals. In between the microphone and the headphones, the crunching sounds were doctored, unbeknownst to the volunteer. The volunteer then rated the freshness and crispness of the chip using the footpedals.

The result? People think potato chips are fresher and crisper when the sound of the crunch is intensified or when only the high frequency sounds were amplified.

I am sure potato chip companies far and wide are now developing louder crunching chips.

There are some delicious-looking drink recipes in the LA Times food section today...perhaps my blog should follow yours and turn into Bartending 101?

Milla: Thank you! The heart is for "I heart potatoes" and "I heart you, my friends!"

Anyanks: I totally think you should! That's what I would do if I wasn't doing a food blog. You should see the crazy cocktails in the cocktail magazine I got J. One has little fruit cubes floating all through it because of some scientific substance used in the drink ... some gelatin or pectin or something. It looks polka dot.

ABOUT THIS BLOG

I've been evaluating my blog and have realized that, while I have lots of nifty posts, I don't really have a good overall explanation of what exactly this blog is all about, and what one can expect to find here. So I'm creating this post and will link to it in the sidebar for anyone who's interested. I am not a professional chef. I have not been cooking for years. I am not an expert who is going to make beautiful and amazing and complicated dishes to "wow" you. I am, in fact, quite the opposite. I am a total beginner. I've always lived in places with miniscule kitchens and concerned myself with schoolwork and studying and working and not paid the least bit of attention to what I was eating every day. And that's what this blog is all about. It's about me learning where my food comes from, how to make it properly, and how to enjoy it to the utmost. It's no fun to learn by myself, so I started the blog to keep track of what I learn, kind of like a

RESTAURANT: Ristorante Belvedere, Monterosso al Mare, Italy

We started off our second-to-last day in the Cinque Terre by taking the train to Vernazza for breakfast: There was supposed to be a market that day, but since the weather was threatening, there were only a few meager stalls, mostly selling non-food items. We had our breakfast and walked around the village a bit. Vernazza used to have a river flowing all the way through it, but now the river has been shunted underground at a certain point. If you walk to the top of town you can see it, along with some ducks and geese that hang out there to get fed by whoever comes along. J. and I then went to sit and have an espresso and wait for the train to Corniglia, the only town we hadn't yet visited. Corniglia is home to the local nude beach (which we skipped) and is the highest of the towns, elevation-wise. We had to walk up a buttload of steps to get there. Look at me go: That's actually me going down (a lot faster than I came up), but I did come up them as well. There is a bus that ta
