I do the same thing, drop about 1ml in a BCC, and adjust flavor, not quite so accurately as you, I just rough estimate percentages by number of drops. some good ideas so far, going to have to think about it. I know what your saying about deciding how to treat case sensitivity, and variation in naming, unfortunately no one uses any kind of standard for it, and many of my recipes came from where ever. Would be nice to be able to select Substitute "Banana" for "banana" in all recipes option, which would also delete the ingredient being substituted.
