Mastering the art of cooking and baking comes down to texture. A dish must taste great and have texture. As an example, adding pineapple, carrots or squash to spaghetti sauce. Carrots in early to simmer down to a favorable mouth feel. Pineapple on the green side, say 20 minutes from serving. Crook neck and zucchini 5 minutes before feed time maintains the body of the squash.
