Two comments.
I think that it would be helpful to indexers to have a complete, searchable, ingredients list. This could be separately accessible from the actual indexing data entry page. (If there were such a thing, I would open it when indexing and keep it open as I do with the Recipe Types list.) It would be fine if it just came up on a web page because that is searchable.This would be an enormous help when it came to figuring out the EYB name for certain ingredients. (For example, chile vs. chili powder -- I had the same problem, and I was indexing an entire cookbook of chili recipes!)
With regard to the specificity of ingredients, there ARE inconsistencies in the existing data, and I was frustrated at the beginning that I couldn't put the exact ingredient in all the time. As some other readers have commented, I felt that I wasn't properly representing the recipe. However, I have come to feel strongly that it is better to err on the side of simplicity in the ingredients list and put specifics that you feel are needed into the recipe notes.
These factors have brought me around to this way of thinking:
1) the most important thing about ingredients is searchabililty; the second most important thing about ingredients is making sure you've got the right ingredients on hand. I used to rank those in the opposite order until I began to make more extensive use of the search capabilities. You can (and probably should) check the actual recipe before starting to making something ... especially something that is demanding as to specific ingredients, like low-fat baking; it doesn't matter so much with something like soup! And for those who looking toward the Shopping List functionality, I'd suggest optionally or automatically including EYB notes on the list in order to pick up specific comments.
2) I've seen some ingredients that strike me as ridicuously specific. Take a look at dark chocolate bars - there are variants with cocoa nibs, toffee and almonds, and hazelnuts, and plain bars. Why stop with those kinds of nuts? Surely there are bars with just almonds, and bars with fruit chunks, etc., etc., etc. Why not include them all? Or look at cherry tomatoes - there are separate ingredients for 6 different colors. Tomatoes have 8 different varieties of canned tomatoes ... really, those aren't all that different from each other! I have observed that recipe-writers are often very specific (to distinguish THEIR recipe from others? due to editorial decisions?) but that from the point of view of usability and consistency within the search engine, EYB needs to draw a line in the sand, somewhere.
That said, the EYB lline has moved over the years - very naturally, as the site has matured - and will probably continue to move. My vote is to try to keep it as simple as possible.
