There are all kinds of cookbooks out there. As our standard living is becoming better and better, people start to pursue healthier and more environmentally friendly, hence more health-focused cookbooks are published.
Don't hesitate, you are on the right path
Recipes are a good and necessary for a cookbook, as they allow us to receive knowledge about cooking from the experts that are ahead of us in an eco lifestyle. However, as a Mr. Einstein once said, "Imagination is more important than knowledge." Even if you know just a little about cooking, you don't need to stop and think about what you are doing. A little bit of creative thought will make the dish yours, truly yours.
