Funny thing is, I can do the "mise en place" routine with a basket full of fresh ingredients and spend an hour or more doing a meal, or I can just go to the cupboard and grab a couple boxes, bags and cans, and the meal is almost as appealing.
I really appreciate learning how to go from field to pantry. Being able to pick something fresh from the back yard, the back porch, or out at a campsite, process it myself, and be able to eat and enjoy it a year or so later is more satisfying sometimes than the great taste of the food itself. Whether it is salmon, elk, mushrooms, wheat, or zucchini, it is a great blessing to take God's bounty and feed myself and others. There is no effort more directly gratifying than harvesting, processing, and preparing good food.
But even so, if all I have is what I got at the grocery store shelf, it is still pretty handy to synergize it into something better than just warm and eat. There's lots you can do to make commercially processed food more appealing.
To that end, the book you suggest is a great tool for folks to work with. Thanks for the link.
