For an upcoming party, my girlfriend and I have been discussing trying to create "potato jenga." The idea is to cook smooth, flat pieces of potato and stack them in a tower, so that everybody has to play a game of Jenga with the potato pieces. If anybody has tried any similar structural potato projects, I'm keen to learn how best to pull it off. (I'll also accept references to other fun ways to get party guests to play with their food, if this project proves impossible.)
So, what method of cooking will make the most suitable potato pieces? I need to avoid warping or a rough texture. Is baking better than frying? Any particular oil I should use if I fry them? High heat or lower heat for more time? I'm at a bit of a loss with where to start because everything I know about cooking relates to the eating, rather than use as a building material!
