The DPP "recipe" includes, I believe, ALL the adjustments you've made to a RAW file in DPP. The approach I use is to pick one shot of a group made under identical conditions (lighting, exposure, lens, focal length if zoom, etc.), make any adjustments, THEN copy that recipe to the clipboard. Then, multi-select all the shots made under the same conditions, and copy the recipe to those photos.
If you copy a recipe from one shot to another image made under different conditions, you may not like the results.
