As you build a recipe you see a list of ingredients on the screen. Although the country of origin for these ingredients may have already been set when the ingredient was created you can choose to adjust this aspect and have it apply to this product / recipe only. 


To access the ingredient declaration fields within the recipe use the drop down arrow to make the extra fields visible.


Any changes you make to the ingredient declarations here will be reflected in the labels / reports for this product but it will not affect the original ingredients.
