Today I spent most of the day cooking with Isabel for our New Year’s Eve dinner party. I was using a cookbook and I realised something. Cookbooks usually have text describing the recipes and pictures illustrating them. When you cook something, you (well, I) inevitably stain the book with sauce or other tasty juices. The great thing is that the food bits staining a recipe tend to be a result (either final or intermediate) of such recipe.
So, in the end, you add flavour (and, why not, smell too) to the cookbook you use.
