Choosing the right idea and distilling it to is essence before building on it, is vital for cooks and novelists. Take the humble corn tortilla as a model. The grocery store version is fine, but the homemade version? Spectacular. Although it’s nothing more than masa and water, the tortilla serves as an exquisite base for creativity. Novelists must learn to take a simple, beautifully constructed idea, too, and once they understand all the possibilities, use it as a springboard for their own creativity.
