NDS Professional allows you to compare, side by side, different versions of the same recipe through the Comparisons tab.
You can go to the comparison tab from the recipe screen:
In the Comparison tab, you will also see the number of the captured versions. Please note that, in order to make easy subsequent comparisons, when you open a ration, it will also be automatically captured in the Comparisons structure and it will be classified as Version 1 or Saved Recipe.
