“As you traverse a slope in French Fries mode, you’ll need to keep those uphill edges biting into the snow. This means pointing your knees and shins a little uphill. A simple way to focus on those edges is to imagine your boots are filled with lemonade, right up to the very top. If you tip them a little, they’ll pour a drink for the snow on the slope. They’ll pour out exactly the same amount from both boots on the uphill side.
If your skis are slipping out of the traverse, this tip will help you get them to bite the snow and hold them on the slope. A friend can ski behind you and call out “pour a drink!” to help keep your skis in the stable French Fries pose.”
