in Fine Cooking:

I keep an extra copy of my favorite cookbook in the car so that when I stop at the supermarket on my way home from work, I can just choose a recipe from the book, jot down the ingredients I need, and run into the store to shop.  Once I'm home, I prepare the recipe using the copy of the book I keep in my kitchen.

Aargh, you're right there at the supermarket.  Why not go in and see what they have before you decide what to cook?
